SITUATION: The timber member BC, inclined at angle θ = 60⁰ to the vertical, is supported by a pin at B and the 0.75-in.-diameter steel bar AC. The moduli of elasticity are 1.8 x 106 psi for timber and 29 x 106 psi for steel. Neglect the weight of BC. 1. Determine the cross-sectional area (in2) of BC for which the displacement of C will be vertical when the 5000-lb force is applied. A. 7.12 C. 5.45 B. 8.97 D. 6.89 2. Calculate the corresponding vertical displacement (in) of C. A. 0.0892 C. 0.0266 B. 0.0619 D. 0.0757 3. Calculate the axial stress (psi) in BC. A. 702 C. 825 B. 586 D. 684 Thanks for watching!
