(10%) Problem 8: Consider a cylindrical cable with a hanging weight suspended from it. 33% Part (a) When the mass is removed, the length of the cable is found to be l0 = 4.55 m. After the mass is added, the length is remeasured and found to be l1 = 5.21 m. Determine Young's Modulus Y in N/m2 for the steel cable if the weight has a mass m = 65 kg and the cable has a radius r =...
