1. Consider a loaded mine cart weighing 3000 lb with 1500 Ib of high-grade ore from an underground mine. Compute the equivalent stiffness and the equivalent static deflection in the wire rope without load and with load. Also, draw the free body diagram of the mechanical system. Let the values of modulus of elasticity and modulus of rigidity to be 30 x 10° psi and 11.6 x 10° psi respectively. (30pts.) Pulley 30" Steel wire rope, 0.05" diameter 25' Loaded mine cart 50°
