Vedclass · Answer

(C) $1$. Longitudinal strain: It is defined as the ratio of the change in length $(\Delta L)$ to the original length $(L)$ of the body. Formula: $	ext{Longitudinal strain} = \frac{\Delta L}{L}$.$2$. Shearing (tangential) stress: It is the tangential force $(F_{tangential})$ applied per unit area $(A)$ parallel to the surface. Formula: $	ext{Shearing stress} = \frac{F_{tangential}}{A}$.$3$. Hydraulic stress: When a body is submerged in a fluid,it experiences a uniform force from all sides,which is equal to the pressure $(P)$ exerted by the fluid. The magnitude of hydraulic stress is equal to the pressure $P = F/A$.

Define longitudinal strain and shearing (tangential) stress and write their formulas. What is the magnitude of hydraulic stress?
