A horizontal rigid bar ABC is pinned at end A and supported by two wires (BD and CD) at points B and C (see the following figure). A vertical load P acts at end C of the bar. The bar has the length of 3.0 m and wires of BD and CD have length of L and L2, respectively. Also, wire BD has a diameter of d= 4.0 mm and modulus of elasticity E = 72 GPa; wire CD has a diameter of d= 3.0 mm and modulus of elasticity E2 = 50 GPa. Please calculate the allowable load P for the allowable stresses in the wires BD and CD are o = 200 MPa and 2 = 172 Mpa, respectively. 2.0 m 1.5 m B D L L2 1.5 m C P
