Q6). For the truss shown below complete the following tasks: Use the method of joints to determine the type and magnitude of the forces in all members. Determine the magnitude and direction of all reaction forces (show all working) a). b). Use a graphical analysis/method to solve the truss. You must include an accurate scaled diagram. 10 KN 20 KN 30 KN 5 KN 15 KN 45 4.0 m 4.0 m 4.0 m 4.0 m RL RR gth Take gravity g = 10 m/s? unless otherwise stated Show all working Note: (1) (2) (3) %3D Weight 45%
