Mechanical Properties of Solids · Elasticity
A metal string A is suspended from a rigid support and its free end is attached to a block of mass . Second block having mass is suspended at the bottom of the first block using a string B. The area of cross sections of strings A and B are same. The ratio of lengths of strings of A to B is 2 and the ratio of their Young's moduli () is 0.5. The ratio of elongations in A to B is .
