Vedclass · Answer

(C) The definitions provided in List-$I$ correspond to the following physical concepts in List-$II$:$(A)$ $A$ force that restores an elastic body of unit area to its original state is the definition of $	ext{Stress} = \frac{F_{	ext{restoring}}}{A}$. If $A = 1$,then $	ext{Stress} = F_{	ext{restoring}}$. Thus,$(A)-(III)$.$(B)$ Two equal and opposite forces acting parallel to opposite faces of a body cause a change in shape without changing volume,which is related to $	ext{Shear modulus}$. Thus,$(B)-(IV)$.$(C)$ Forces acting perpendicular everywhere to the surface per unit area,which are the same everywhere,result in volumetric stress,which is related to $	ext{Bulk modulus}$. Thus,$(C)-(I)$.$(D)$ Two equal and opposite forces acting perpendicular to opposite faces cause a change in length,which is related to $	ext{Young's modulus}$. Thus,$(D)-(II)$.Therefore,the correct matching is $(A)-(III), (B)-(IV), (C)-(I), (D)-(II)$.
