full working step and explanation

Figure 1 shows a truss with loads and supports. At A, it is pin connected and roller connected at E. a) Draw the free body diagram of the truss. (3 Marks] b) Evaluate the reaction force at joint A and E. [6 Marks] c) By using the method of joints, determine the force in member CD and GD. Similarly, determine the force in member CG and FG. State whether the members are in tension or compression. [11 Marks] 13 KN 13 kN 13 KN 13 kN 1 2 m 2 m 2mm VD 2.5 m 6 F
