A cable is replaced by another one of the same length and material but twice the diameter. How will this affect the elongation under a given load ?

Two wires A and B have equal lengths and are made of the same material. But the diameter of A is twice that of wire B. Then for a given load

Two wires A and B have the same cross section and are made of the same material but the length of wire A is twice that of B. Then for a given load

Four wires made of the same material are stretched by the same load. Their dimensions are given below. Which one will be elongated most?

Two strings of the same length and material are stretched under the same tension . If the ratio of their diameters is 4 : 3 , what is the ratio of the frquencies of their fundamental tones ?

A wire of initial length L and radius r is stretched by a length l. Another wire of same material but with initial length 2L and radius 2r is stretched by a length 2l. The ratio of the stored elastic energy per unit volume in the first and second wire is,
