Explain hydraulic stress, volume stress and volume strain

Answer» <html><body><p></p>Solution :In above figure, a solid body placed in the fluid under high pressure is compressed uniformly on all sides. <br/> The force applied by the fluid acts in perpendicular direction at each point of the surface and the body is said to be under hydraulic compression. As a result this leads to decrease in its volume without any <a href="https://interviewquestions.tuteehub.com/tag/change-913808" style="font-weight:bold;" target="_blank" title="Click to know more about CHANGE">CHANGE</a> of its geometrical shape.The body develops internal restoring <a href="https://interviewquestions.tuteehub.com/tag/forces-16875" style="font-weight:bold;" target="_blank" title="Click to know more about FORCES">FORCES</a> that are equal and <a href="https://interviewquestions.tuteehub.com/tag/opposite-1137237" style="font-weight:bold;" target="_blank" title="Click to know more about OPPOSITE">OPPOSITE</a> to the forces applied by the fluid.<br/>The internal restoring force per unit area in this case is known as hydraulic stress and its <a href="https://interviewquestions.tuteehub.com/tag/magnitude-1083080" style="font-weight:bold;" target="_blank" title="Click to know more about MAGNITUDE">MAGNITUDE</a> is equal to the hydraulic pressure (applied force per unit area). <br/> The strain produced by a hydraulic pressure is called volume strain and is defined as the ratio of change in volume `(DeltaV)` to the original volume (V) Volume strain `=(Delta )/(V)` <br/> It has no units or dimensional formula.</body></html>
