A rigid bar AB of length L = 66 in. is hinged to a support at A and supported by two wires attached at points C and D. Both wires have the same cross-sectional area (A= 0.0272 in. squared) and are made of the same material (modulus E = 30 × 106 psi). The horizontal distances are c = 20 in., and d = 50
