Want this question answered?
Pressure describes a load acting over an external surface. Stress describes the loading within the material. This is often caused by the material deforming so that one part presses against another. So if the loading has an external source acting over an external area it is pressure, if the loading is internal and distributed over a cross section of the material it is stress.
1) zero stress on elastic material/it's at original position 2) stress is applied/deformation occurs 3) release of energy (earthquake) 4) elastic material rebounds
Stimulus :)
No
family stress
Earthquakes release the energy of frictional stress in forms of seismic waves.
shock
stress changes the earth's surface by the way it looks and the layers.
earthquake
No, stress is a force that adds energy to rocks.

relieve stress
this type of energy is used when the body is put under stress
elastic energy
exhaustion
The expression for the energy density in terms of stress and strain can be expressed as ρe.
No. They do not give you energy. They relieve stress on your muscles.
