Young's modulus of a rod is `(AgL^2)/(2l)` for which elongation is `lamda` due to its own weight when suspended from the ceiling. L is the length of the rod and A is constant, which is:

A uniform rod of length L , has a mass per unit length lambda and area of cross section A . The elongation in the rod is l due to its own weight, if it suspended form the celing of a room. The Young's modulus of the rod is

A copper rod length L and radius r is suspended from the ceiling by one of its ends. What will be elongation of the rod due to its own weight when p and Y are the density and Young's modulus of the copper respectively?
