Question 1 The loads F 1 = 440 N and F 2 = 160 N act as shown on the truss in Figure Q1. Determine the reaction forces at A and B as well as the magnitudes of the axial forces in all the members of the truss. Indicate whether the members are in tension (T) or compression (C). Assume there is a roller type joint at B is and a pin type joint at joint C. [FAB = 531 N (T), FAC = 183 N (T)] Figure Q Question 2 Determine the reaction forces at A and C, as well as the forces (in terms of W,) in each of the members of the loaded truss shown in Figure Q 2 , and state whether they are in tension or compression. Figure Q 2 Question 3 In Figure Q3, the plane truss ABCDEHGFA forms part of the supports of a crane on an offshore oil platform. The crane exerts two forces, each of magnitude 122.5-kN, and acting vertically downwards on truss joints B and D. Determine the magnitudes of the axial forces in members AB, BC, EH and GH of the truss, and state whether they are in equilibrium or not. Figure Q 3 y x
