Shear stress, often denoted by τ (Greek: tau), is the component of stress coplanar with a material cross-section. Shear stress arises from the force vector component parallel to the cross-section of the material. Normal stress, on the other hand, arises from the force vector component perpendicular to the material cross-section on which it acts.
Shear stress arises from shear forces, which are pairs of equal and opposing forces acting on opposite sides of an object.see more at WikipediaCheck More at http://personal.effectsofanxiety.net/
The relationship between the stress and strain that a particular material displays are known as that particular material’s stress-strain curve. It is unique for each material and is found by recording the amount of deformation (strain) at distinct intervals of a variety of loadings (stress). These curves reveal many of the properties of a material (including data to establish the Modulus of Elasticity, E).
Generally speaking, curves representing the relationship between stress and strain in any form of deformation can be regarded as stress-strain curves. The stress and strain can be normal, shear, or mixture, also can be uniaxial, biaxial, or multiaxial, even change with time. The form of deformation can be compression, stretching, torsion, rotation, and so on. If not mentioned otherwise, stress–strain curve refers to the relationship between axial normal stress and axial normal strain of materials measured in a tension test.The Walker Brothers – The Sun Ain’t Gonna Shine AnymoreConsider a bar of original cross sectional area A being subjected to equal and opposite forces F pulling at the ends so the bar is under tension. The material is experiencing a stress defined to be the ratio of the force to the cross sectional area of the bar, as well as an axial elongation:σ=FA0{displaystyle mathrm {sigma } ={tfrac {F}{A_{0}}}}ϵ=L
−L0L0=Δ
LL0{displaystyle mathrm {epsilon } ={tfrac {L-L_{0}}{L_{0}}}={tfrac {Delta L}{L_{0}}}}
Subscript 0 denotes the original dimensions of the sample. The SI unit for stress is newton per square meter, or pascal (1 pascal = 1 Pa = 1 N/m2), and for the strain is “1”. Stress-strain curve for this material is plotted by elongating the sample and recording the stress variation with strain until the sample fractures. By convention, the strain is set to the horizontal axis and stress is set to a vertical axis. Note that for engineering purposes we often assume the cross-section area of the material does not change during the whole deformation process. This is not true since the actual area will decrease while deforming due to elastic and plastic deformation. The curve assuming the cross-section area is fixed is called the “engineering stress-strain curve”, while the curve based on the actual cross-section area is the “true stress-strain curve”. If not mentioned otherwise, the relationship between the true stress-strain curve and the engineering stress-strain curve will be discussed later.see more at WikipediaCheck More at http://workout.vydio-x.com/
Everyone gets stressed out now and then, but chronic stress causes much more wear and tear on the body than most people realize.
Chronic stress is a hard thing to describe to family, friends, and sometimes even doctors. They can’t see it like they would a broken arm or a flesh wound, which may cause some to doubt its very existence.
However, anxiety is a very real disorder that effects 18 percent of the American population. When it rears its ugly head, so do many other physical side effects. Here are 10 of the most common.
1. Heart disease

You know that saying, “You’re going to give me a heart attack?” Well, anxiety and panic attacks might actually do that. High blood pressure and weakened heart muscles are both side effects of stress that raise your chances of having a heart attack and/or developing cardiovascular disease.
2. Loss of libido

With all these negative things happening in your body, it’s not a big surprise that your libido can suffer. Part of this is because your hormones aren’t functioning properly, and another is that your mind and body are distracted. It’s important to communicate with your partner and remember that you don’t “owe” anyone sex.
3. Brain damage

Years of extreme stress and anxiety can lead to brain damage, particularly early-onset Alzheimer’s. It’s been found that the cortisol that’s released during stressful periods actually kills the hippocampus, leading to loss of memory and premature brain aging.
Brain researcher Don Joseph Goewey explains how to utilize a habit loop to relieve stress and how to use the 90-second clear button technique to circumvent stress before it spirals out of control.Watch more on The Dr. Oz Show: https://bit.ly/2wTEd3k

http://www.howdini.com/howdini-video-6638787.htmlSome of us panic under pressure, others freeze when we’re stressed. Here’s how to stay focused under stress, from family and lifestyle journalist Ylonda Caviness.Managing Stress – How to deal with stress
http://www.howdini.com/howdini-video-6638754.htmlEver notice your neck and shoulders hurt after a stressful day? You’re probably holding a lot of tension in those muscles. Here are some stress relief tips and exercises for your body after a rough day, from family and lifestyle correspondent Ylonda Caviness.Stress relief tips and exercises – How to relieve stressStress not only makes you feel lousy and ill-tempered, it can literally be a killer. It’s important to find outlets for stress relief and identify its sources as well.* First, you must recognize that you are stressed. It’s more than likely just you and not everyone around you who is stressed as that moment.* To relieve stress, you need to identify the source of it. Often just your day-to-day tasks can cause a great deal of stress.* Exercises you can do almost anywhere for stress relief:
1. If you are in your car rushing to get somewhere and trying to beat a light, simply stop and let the light catch you. Take deep breaths while sitting at the light and tell yourself “The tension is flowing out of my body.”2. You can also simply shrug your shoulders and hold it for 4-5 seconds. A lot of tension is held in your shoulders.3. Listening to music can help relieve stress. Put on some silly music that will allow you to have fun and lighten up.4. Laughter is the best prescription for stress relief – even try to laugh at yourself.* Recognize that its not just you who is stressed out—everyone goes through stressful situations.
This video is intended to spread awareness about the long-term effects of stress. Everyone experiences stress everyday, it can come from any source. Some examples include emotional, physical or job related stress. Stress is our body’s primitive way of responding to any kind of internal or external demand or threat. The short-term effects of stress may not be serious but prolonged exposure to stress can lead to very serious long-term effects on the body.
Thus, this video will be outlining the some of the long-term effects on the body such as an increase in heart attacks, obesity and development of diabetes. This video will also be discussing the three stress hormones; cortisol, epinephrine and norepinephrine. Cortisol, which is the major stress hormone, is released from the adrenal cortex. Epinephrine which is also referred to as adrenaline and norepinephrine, referred to as noradrenaline are released from the adrenal medulla.This video was made by 4DM3 students Vyshnavi Mahendran, Tamandeep Khangura, Humaira Nakhuda, Mateen Akhtar and Andrew Nashed.

Obviously a made-up mental disorder is the logical result of anxiety over made up science. This is reminiscent of the anxiety disorder liberals were suffering when they couldn’t accept that Al Gore had lost the election. That may have been the point of no return for many on the left’s sanity. Now crazy is the standard for Al Gore and his prophets of doom.
Some climate scientists afflicted by "pre-traumatic stress disorder" b/c no one takes their research seriously.

“In the U.S., [climate change] isn’t well-supported by the funding system, and when I give public talks in the U.S., I have to devote the first half of the talk to [the topic] that climate change is really happening,” says Parmesan, now a professor at Plymouth University in England.
Parmesan certainly isn’t the first to experience some sort of climate-change blues. From depression to substance abuse to suicide and post-traumatic stress disorder, growing bodies of research in the relatively new field of psychology of global warming suggest that climate change will take a pretty heavy toll on the human psyche as storms become more destructive and droughts more prolonged. For your everyday environmentalist, the emotional stress suffered by a rapidly changing Earth can result in some pretty substantial anxieties.
The climate change religion has already established its notions of sin, penance, and indulgences. Now they’re canonizing martyrs and saints.
@RyanMaue that is what happens when reality surpases fiction.

Hi everyone else! This video clip is probably be about maladaptive daydreaming and fantasizing, precisely what its and how to handle it. What is maladaptive daydreaming? Well, theoretically it is actually fantasizing, dissociation and now we additionally’ve all skilled this. Thinking about something in your ideas and dissociating from just what is being conducted all around us. We are able to be lost in idea for some moments, moments, or to a severity, hours or maybe more. This, averagely, is completely regular and absolutely nothing to worry about.
But, like most such thing, it may become difficult and stay mistreated and be an addiction. Consequently, when does it turned out to be a problem? Really, maladaptive daydreaming occurs when it becomes an addiction and you are clearly clearly spending longer in your mind, and neglecting your outer globe, eg friends and family, family, college, those forms of things. Often times it’s a coping method, dissociation, perhaps for anxiety, tension, despair. And, nothing is incorrect with that on it’s own. As a matter of fact its an excellent power to have and I in addition did a video committed to finding your internal leisure area if you are interested in checking that-away. It is an area you produce in your head that will allow you to launch any stress and anxiety you’ve got and just unwind. Which wonderful, it is a type of meditation, and meditation the most helpful things to do for your mind, body, and spirit.
It might be an incredibly spiritual practice and enable you to connect and comprehend yourself on a much deeper degree. In addition to change you into way more innovative and imaginative. Building these wonderful capabilities. It could end up like a lucid dream. Therefore, those will be the positives for this, or in other words, when you’ve got control about it that is staying away from over yourself.
It becomes maladaptive daydreaming or serious fantasizing when, as I mentioned previously, it makes you invest so much period of time in here and not-out right here, neglecting things which are vital that you you in your external globe. Coping process or a solution to release panic and anxiety is very good, but addiction and neglect of your exterior globe is bad. So, I believed I would personally share some personal information about at this point you of that time period that i’ve been lost in thought when it comes to is difficult and unpleasant for me personally. Times when it ended up being uncontrollable.
So, as soon as I’m maybe not absolutely doing anything or once I get sidetracked from doing a thing, i will be able to be soaked up whenever you consider the tips of my mind. Mainly it is negative thoughts, thinking and worrying all about blunders i’ve made, upcoming worries that will cause me anxiety and stress, awful ideas. I really could turned out to be for that reason immersed in what i will be thinking so it exhibits into my genuine body. Associated with, frequently i shall talk aloud the things I became thinking and therefore catches me off-guard.
Other times i’ll imagine some real sensation, like let us show someone hitting me, or any other discipline, and I also can actually feel it straight back at my body. In other instances i will imagine something mental and I reenact that within my brain and I also also can make myself go into a tremendously various sensation than I became in prior to thinking about it. And, which very interesting indeed. And, there’s nothing wrong with actually experiencing what you could be thinking given that it goes to show precisely how efficient the thoughts are.
You consider something and you’ll actually feel what you imagined, in all kinds of practices. So, you should utilize by using good motives to enhance the conventional of the everyday life. It truly is very useful actually. The thing I suggest is, considering any such thing good that produces you’re feeling great about yourself, tends to make you actually feel those thoughts and real emotions. But, there are several alternative methods of managing this type of behavior that I will discuss today. What exactly are some way of working with maladaptive daydreaming and severe fantasizing? Well, the very first most critical thing is learn how to get a grip on it. But, precisely how you may not repeat this? Actually, 1st thing is learn to recognize the behavior and want to change it. You simply can’t change it away if you’re going to be reluctant or cannot recognize it. You need to just take that effort first. Once you have done that, discover exactly what is causing that do that? Could it be being set off by something? If so, what-is-it and just why? If a very important factor is causing it, often there is a reason.
If you are not being triggered, why else have you been carrying it out? Might it be an escape from life, a coping method, possibly an addiction? Perchance you feel well informed in the inner globe helping to make you want to be here more in place of your outer globe. Or, possibly its uncontrollable accessible and yourself don’t understand you might be carrying out it. If it could be the scenario, it truly is regularly because of it either becoming triggered or a coping equipment or addiction.
If you have no idea how-to control the dissociation, a rehearse we give should be to intentionally dissociate yourself with a positive bring about order to master when the boundary is and just how to manage it. Generally speaking meditation and self-hypnosis often leads you to mastering that skill that we recommend. Dedicate a place and time day-to-day, including a timeframe, allowing yourself to become totally immersed into this fantasy to release those negative thoughts and obtain things you need from it.
From then on let yourself return. In addition, whenever you produced a world to unwind, which is great. But, regarding becomes an addiction it is time to re-evaluate the reason why you produced this globe. It had beenn’t to call residence in. Consequently, you need to get straight back on the right track as to why this globe is out there in 1st location. Make targets for yourself. Whether or not it’s a bad area or negative thoughts are building causing you to physically react to those, like We described with my example whenever i believe of upheaval and I can feel it, actually and emotionally, carefully shift your awareness of one thing good that may lead you to feel a lot better really and psychologically.
Think about your achievements, your targets, what you would like your perfect life to-be like. Shift from the bad globe into a confident globe. Again, usually do not make it an addiction to the level in which it is all of that’s necessary doing is maintain that world. Including, if you’ve got more self-confidence within internal world and that’s why you may invest much time here, transfer that to your external world. Imagine, visualize your confident self from your inner globe although the person who you may be everyday inside exterior world.
Perhaps imagine in your head two yous. The secure the one which is out there within your head, along with several other one that won’t have self-confidence this is actually who you really are in day-to-day life. From then on maybe imagine them merging into one. To make sure you are confident perhaps not just within internal globe, but also whenever you glance at the exterior world. Officially this could be hypnosis.
You might be hypnotizing yourself to be a tad bit more confident. That may work tremendously if you keep at it. And in addition much better, along with your imagination and dissociation abilities, it willn’t even be tough to help you try. Just visualize and imagine like you regularly do. Utilize those abilities since this is obviously what is going to assist you. It is a great capability to possess because you can put on it to your benefit, in a controlled environment to hypnotize your self, and provide oneself recommendations to better your behavior. Since dissociation takes place with hypnotherapy, this can really help you as you are often very hypnotizable. Precisely what should-be mentioned is the fact that people with skilled trauma tend to be a whole lot more hypnotizable than those havingn’t which could make all of them way more suggestible. So, make use of that capability to your advantage. It is a trade off in a way getting really hypnotizable. You could be at risk of these types of conditions where maybe it’s uncontrollable and you are clearly dissociating, but when you can figure out how to handle that ability you have got, you should employ it with exceptionally positive effects.
So, that is the strategy that you should notice it. There is completely nothing unfavorable, just a trade from something you need to learn just how to utilize ability precisely. Not just that, if you may be having a concern coming to the exterior globe from this dream, develop a portal to get back. I have a portal in my inner relaxing place that enables us to get back to myself from a fantasy. We talked about this within my finding your internal soothing place video that i might have one of the links in the description. But, imagine a portal that should you walk through it, you are likely to get right up from this fantasy, but will hold the good attributes you’d in your daydream. After adequate attempts of having up out of bed after going right on through this portal, it can become conditioned and you also can manifest it whenever you know that you are inside problem and return to on your own.
Once more, it truly is about learning that boundary and utilizing control of it. So fundamentally, fantasizing and daydreaming, possibly even on point of having a lucid dream, are not irregular in any way which is anything we-all experience with different amounts. It might be beneficial. It’s a wonderful coping equipment, in moderation.
But, for people who tend to be addicted or cannot get a grip on it, maladaptive daydreaming, this is the right time for you to re-evaluate the reason why this world is present within mind, and discover that boundary between inner vs external world. Enabling you to ultimately become confident individual in your daydream so that you don’t have to escape to your internal globe to be that confident person. Bring all of them straight down as it is both you and you are see your face if you decide to try. Consequently, kindly share your experiences and I also additionally hope this movie ended up being informative and helpful.
