2. The principal load bearing structure for a proposed bariatric hoist is shown in figure Q2-1, and consists of a pin-jointed truss attached to an upright beam. 1 1 B S E D Mg h Figure Q2-1: Proposed structure of a bariatric hoist. a) Consider the pin-jointed truss shown with pins at A, B, C, D and E and with a load mass of Mg as shown. Calculate the reaction forces at A and C as well as the force in the link BE. (6 marks) b) Using the results from part (a) draw a shear force and bending moment diagram of beam. You can ignore the compressive force along the principal axis of the beam, but show clearly the dimensions h and s. (6 marks)
