To determine

To identify and draw: The two force members and the free body diagrams of each member of the frame.

Explanation of Solution

Assumptions:

  • Consider the state of member as tension where the force is pulling the member and as compression where the force is pushing the member.
  • Consider the force indicating right side as positive and left side as negative in horizontal components of forces.
  • Consider the force indicating upside is taken as positive and downside as negative in vertical components of forces.

Show the free body diagram of the member of the frame as in Figure (1).
