9. An elevator on a construction site is being operated at rated capacity of 6 tons, and is supported by two standard steel cables, each having a cross-section area of 1.25-in.2 and an effective modulus of elasticity of 12 * 106 psi. As the elevator is descending at a constant 500 ft/min, an accident causes the top of the cable, 200 ft above the elevator, to stop suddenly. (a) Calculate the Impact Factor. (b) Estimate the maximum elongation and maximum tensile stress developed in cable. (c) Estimate the maximum elongation and maximum tensile stress developed in cable if the cable length was 100 ft. (d) Comment on the effect of changing cable length on maximum tensile stress developed in the cable.
