A rigid weightless bar is supported by 2 steel (yield strength=100ksi, E=29,000, and A=1.6 sq. in.) cables and an aluminum (yield strength=70ksi, E=10,600, and A=3.2 sq.in.) cable. Determine largest load P that can be applied without any cable exceeding its yield strength. Bar length in 10 ft with aluminum directly in the center and steel cables 5 feet on either side. Steel cable lengths are 8 ft and aluminum cable is 10 ft. Load P is in the center.
