A wire of cross section A is stretched horizontally between two clamps located 2l m apart. A weight W kg is suspended from the mid-point of the wire. If the mid-point sags vertically through a distance x<1 the strain produced is then its new length becomes Young's modulus of rubber is 10^4 N/m^2 and area [...]
Two identical wires of iron and copper with their Young’s modulus in the ratio 3:1 are suspended at same level. They are to be loaded so as to have the same extension and hence level. Ratio of the weight is

A piece of copper wire has twice the radius of a piece of steel wire. Young’s modulus for steel is twice that of the copper. One end of the copper wire is joined to one end of the steel wire so that both can be subjected to the same longitudinal force. By what fraction of its length will the steel have stretched when the length of the copper has increased by 1%?
