Document Summary
Fall 2012: write your name and section number on your bluebook and test paper, no questions about the test problems will be allowed once the exam begins. Determine the force p required to support the 50 lb force using the frictionless pulley system shown. At pulley b, the cable from pulley c is fixed at its center. The weight is also attached to pulley b at its center. For the cross-sectional area shown, the centroid has been located at point c and all dimensions given. Determine a) ix" b) iy" c) ix",y" d) the principle axes e) the principle moments of inertia. Determine the magnitude and location from the water surface of the hydrostatic force acting on gate ab, which has a width of 2 m. = 62. 4 lb/ ft3. Weights f and g are connected together using a rope that passes around three rough drums. If the coefficients of static friction are a = 0. 2, b =
