The timber member BC, inclined at angle ϴ=600 to the vertical, is supported by a pin at B and 0.75in. diameter steel bar AC. (a) Determine the cross-sectional area of BC for which the displacement of C will be vertical when 5000lb force is applied. (b) Compute the corresponding displacement of C. The moduli of elasticity are 1.8 x 106 psi for timber and 29 x 106 psi for steel. Neglect the weight of BC.
