A roof truss is loaded and supported as shown in Figure 2. The joints are all pinned. Take L = 3 m and e = 35°. (a) If P = 500 N, determine the support reactions at A and D. (b)If P = 500 N, find the forces in all the members of the truss. State whether each of the members is in tension or compression. (c) Determine the maximum magnitude P of the two loads that can be applied to the truss, if the maximum allowable tensile force in the members of the truss is 2 kN and the maximum allowable compressive force is 1.2 kN.
