As shown in the figure, three wires with different areas and modulus of elasticity are used to lift a load W. Their unstressed lengths are L1, L2, and L3. (a) What stress exists in the longest wire, and (b) shortest wire? (c) Determine the stress in the shortest wire if W = 500 Ib. (d) What should be the load so that the two wires will stretch to the length of the longest wire?
