1. Find the increase in pressure required to decrease the volume of a water sample by 0.01 %. Bulk modulus of water is 2.1 x 109 N/m2
2. A steel plate of face-area 4 cm2 and thickness 0.5 cm is fixed rigidly at the lower surface. A tangential force of 10 N is applied on the upper surface. Find the lateral displacement of the upper surface with respect to the lower surface. Rigidity modulus (shear modulus) of steel is 8.4 x 1010 N/m2.
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
