Chapter 4.5, Problem 4.38P
The load of 2000 lb is to be supported by the two vertical steel wires for which σγ = 70 ksi. Originally wire AB is 60 in. long and wire AC is 60.04 in. long. Determine the force developed in each wire after the load is suspended. Each wire has a cross-sectional area of 0.02 in2 Est = 29.0(103) ksi.
