Question: Consider a cylindrical cable with a hanging weight suspended from it.
A) When the mass is removed, the length of the cable is found to be l0 = 4.76 m. After the mass is added, the length is measured and found to be l1 = 5.49 m. Determine Young's Modulus Y in N/m2 for the steel cable if the weight has a mass m = 35 kg and the cable has a radius r = 0.015 m.
B) 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 , l1, l0, and r provided in part A.
