1. Determine the force in each member of the truss below and state whether each member is in
tension or in compression

2. The internal drag truss for the wing of a light airplane is subjected to the forces shown below.
Determine the force in members BC, BH, and HI and state whether each member is in tension or
compression.

3. Determine the forces exerted on member CDE by roller support E, cable BD, and member ABC. w
is the magnitude of the distributed load at the top of the diagram, and is equal to 300 N/m.

4. A beam is supported by a ball-and-socket joint and two cables as shown below. Determine the
reaction forces at support A and the tension in the two cables.
