Question: When a hoisting cable is long, the weight of the cable itself contributes to the elongation. If a cable has a weight per unit length

When a hoisting cable is long, the weight of the cable itself contributes to the elongation. If a cable has a weight per unit length of w, a length of l , and a load P attached to the free end, show that the cable elongation is δ = Pl/AE + wl2/2AE
