A wire AB of radius 0.3 mm and length 300 cm is attached to a fixed support at its ends A and it hangs vertically. The wire carries a load 39.2N attached to its mid-point and also another load of 39.2N at its lower end B. IF Y for the material of the wire is 2 times 10^12 dyn.cm^-2, find the elongation of the end B.
