Use static equilibrium equations to solve for AD and AB. Solve for AD by calculating y direction static equilibrium. Solve for AB by calculating x direction static equilibrium. Draw the free body diagram for joint C.

Calculate CE x. Calculate CE y. Use static equilibrium equations to solve for CE and CB. Solve for CE by calculating y -direction static equilibrium. Solve for CB by calculating x direction static equilibrium. Draw the free-body diagram for joint E. Calculate EB y. Finally, draw a box and add arrows for each existing force in the appropriate direction; label each force arrow according to its type. If necessary, refer to the list of forces and their description in order to understand the various force types and their appropriate symbols.
