Problem 3c.1: The bar ABC is pinned at A and there is a roller support at B. The bar has a distributed load applied from A to B and a moment at end C. The bar also has a uniformly distributed weight of w = 5 lb/in. Determine the support reactions at A and B. Use the given values of h = 15 lb/ft; Mc = 900 lb-in; L = 10 ft. Answers: RA = 463.75 lb RB = 186.25 lb

A non-uniform beam AB, of mass 60kg and length 8a metres, rests in equilibrium in a horizontal position on two vertical supports. One support is at C, where AC = a metres and the other support is at D, where DB = 2a metres, as shown in Figure 2. The magnitude of the normal reaction between the beam and the support at D is three times the magnitude of the normal reaction between the beam and the support at C. By modelling the beam as a non-uniform rod whose centre of mass is at a distance x metres from A, (a) find an expression for x in terms of a. A box of mass M kg is placed on the beam at E, where AE = 2a metres. The beam remains in equilibrium in a horizontal position. The magnitude of the normal reaction between the beam and the support at C is now equal to the magnitude of the normal reaction between the beam and the support at D. By modelling the box as a particle, (b) find the value of M.
