1. Determine the force in each member of the truss below, and state whether each member is in tension or in compression.
2. A beam is supported by a ball-and-socket joint and two cables as shown bebw. Determine the reaction forces at support A and the tensions in the two cables.
3. Determine the forces exerted on member CDE by roller support E, cable BD, and member ABC. W is the magnitude of the distributed bad at the top of the diagram, and is equal to 300 N/m.
