Problem 2.4-15A rigid bar ABof length L5 66 in. is hinged to a supportat Aand supported by two vertical wires attached at points Cand D(seefigure). Both wires have the same cross-sectional area (A5 0.0272 in.2) andare made of the same material (modulus E 5 303106psi). The wire at Chas length h 5 18 in. and the wire at Dhas length twice that amount. Thehorizontal distances are c 5 20 in. and d 5 50 in.(a) Determine the tensile stresses sCand sDin the wires due to theload P5 340 lb acting at end Bof the bar. (b) Find the downward displacement dBat end
