Yes stress exists and it causes one to get stressful . It is a very bad thing. It causes the body to go in trauma.
Poor morale or where a problem exists
Wherever there is stress there is strain. In the example you noted, if heated bar expands freely without one end constained it changes its strain without stress; that strain is called eigenstrain. If the same bar is held rigidly then the eigenstrain resisted and you get stress and strain. So stress cannot exist without strain; but strain can exist without stress if it is eigenstrain.
Gravity exists because mass exists.
Galaxy exists because stars and nebulae exists.
Do you mean getting stressed because you don't have a job? There are bills to pay every month and if you don't have a job, you won't have money to pay those bills. If you go through this long enough, you may have your car, apartment or home taken away. So knowing that this may come sooner or later causes stress. Or did you mean a "stress-less job"? I don't believe that exists.
Stressing an equilibrium system involves changing the conditions of the system to disturb the equilibrium. This can be done by changing the temperature, pressure, or concentration of reactants/products. Stress can be applied by adding or removing reactants/products or changing the temperature or pressure of the system.
Currently we have is grammatically correct.
A certain amount of stress is necessary for people to perform any sort of work. A problem with stress develops when the pressure to perform a task interferes with how safely the job is done. Injuries can increase when people are not focusing on the job at hand, or when they are expected to perform tasks beyond their physical capabilities. In Queensland the 1980's a workers compensation stress claim set a precedence in law when a decision was made that if stress contributed to even 1% of the injury, the claim was accepted. An avalanche of stress claims followed, many having very little to do with "stress". Today, it is very much harder to prove stress as the causal factor in workplace injuries, but it most certainly exists. Managing stress and preventing work injuries is all about risk assessing the type of job, how it is done, ensuring adequate training, good work ethics, safe work practices, and good management skills.
good stress, medium stress and bad stress
Why the tomb exists in egypt
Tension stress tends to pull a material apart and acts normal to its cross section plane. Shear stress tends to shear a material apart and acts in the plane of its cross section plane. Crushing stress tends to push a material and acts normal to its cross section plane, in the opposite direction of tension. Crushing stresses are compressive stresses and could also be bearing stresses. For a material laoded in pure tension, shear exists at 45 degrees along the cross section plane and is 1/2 the tensile value. For pure shear, tension exists 45 degrees along the cross section plane and is equal to the shear value. Most all metals are stronger in tension than in shear, by a factor of about 1.7. Some materials, like chalk or concrete, are stronger in shear than in tension. If loaded in shear, they will break intension 45 degrees along the cross section
