Consider a cylindrical cable with a hanging weight suspended from it. When the mass is removed, the length of the cable is found to be l0 = 4.53 m. After the mass is added, the length is remeasured and found to be l1 = 5.46 m. Determine Young's Modulus Y in N/m2 for the steel cable if the weight has a mass m = 85 kg and the cable has a radius r = 0.045 m. If we were to...
