Review Problem #1: A beam is held in equilibrium by a pin at A and a cable BDE that wraps over a frictionless pulley at D, which has a radius of 0.1 m. The beam supports a vertical force of P = 8 kN, as shown below. Neglect the weights of the beam and pulley in this analysis. Calculate the internal force(s) and moment(s) at point C.
Review Problem #2: For the shaded area shown below, calculate the following quantities: (a) Vertical location of the centroid (y coordinate) with respect to the bottom edge of the area. (b) Moment of inertia about a horizontal axis through the centroid (I Cx ). Note: For a semicircular area,

Unformatted text preview: Problem 4.45: Problem 4.46: Problem 4.47: Problem 4.48: Problem 4.49: Problem H.01: A rigid bar ACEB is supported by a pin at A and by two rods CD and EF. A horizontal load of 2 kip is applied at the location shown. Each rod is made of aluminum (E = 10 × 10 6 psi) with a diameter of 1.0 in. Before loading, the rods were unstressed and the bar was vertical. Calculate (a) the internal forces in rods CD and EF, and (b) the deflection of point B. Problem H.02: The rigid bar ABCD shown below is supported by four identical, equally spaced wires. Find the tension in each of the wires in terms of the applied load P. Assume P and L are known quantities....
