Question

Problem 1 The load of 2800 lb is to be separated by the two essentially vertical A-36 steel wires (E 29.0x103 ksi). If originally wire AB is 60 in. long and wire AC is 40 in. long, determine the cross-sectional are of AB if the load is to be shared equally between both wires. Wire AC has a cross-sectional area of 0.02 in2. 60 in. 40 in.
