Consider a cylindrical cable with a hanging weight suspended from it. Part (a) When the mass is removed, the length of the cable is found to be l, = 4.51 m. After the mass is added, the length is remeasured and found to be l = 5.46 m. Determine Young's Modulus Y in N/m- for the steel cable if the weight has a mass m = 65 kg and the cable has a radius r= 0.035 m. Part (b) If we were to double the radius of the wire and re-suspend the weight, which of the following would be correct. Part (c) If this cable is pulled down a distance d in m from its equilibrium position it acts like a spring when released. Write an expression determining the spring constant k of this material using the cable-specific variables Y,l, lo, and r provided in part A.
