Consider a cylindrical cable with a hanging weight suspended from it. 1) When the mass is removed, the length of the cable is found to be l0 = 4.58 m. After the mass is added, the length is remeasured and found to be l1 = 5.27 m. Determine Young's Modulus Y in N/m2 for the steel cable if the weight has a mass m = 55 kg and the cable has a radius r = 0.045 m. Y = 2) 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. k =

Consider a square-faced beam supporting a section of a building. a) Before installation, the length of the beam is found to be l0 = 15.02 m (figure a). After installation and construction, the length is remeasured and found to be l = 14.98 m (figure b). Determine Young's Modulus Y in N/m2 for the beam if it supports a mass m = 35000 kg and has a side length d = 1.9 m. b) Suppose that after the beam is installed it needs to be repaired. The weight it supports is removed and replaced with a new mass m2 (figure c). After the new mass is supported, the side length is remeasured and found to be larger with a difference of Δd. Assuming that this side length deformation is uniform and small, write an expression for determining Poisson's ratio v for this beam if its Young's modulus Y is known.
