96. Copper wire length l = 80 cm and a cross-section S = 8 mm2 mounted at one end in the suspension device, and its other end attached to the load weight m = 400, the pull wire with a cargo of rejecting up to the height of the suspension, is released. Considering wire weightless, determine its extension at the bottom point of the trajectory of movement of cargo. Young´s modulus of copper = E 118 GPa.
