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 [...]
