Density of rubber is d. A thick rubber cord of length L and cross-section area. A undergoes elongation under its own weight on suspending it. This elongation is proportional to

Elongation of a wire under its own weight is independent of

A wire of length L and cross section A hung from a rigid support is loaded with a mass M The elongation produced is

A metallic rod of length l and cross-sectional area A is made of a material of Young's modulus Y. If the rod is elongated by an amount y,then the work done is proportional to

A metallic rod of length l and cross-sectional area A is made of a material of Young's modulus Y. If the rod is elongated by an amount y,then the work done is proportional to

A uniform cylindrical rod of length L and cross-sectional area by forces as shown in figure. The elongation produced in the rod is
