Ascissors truss supports three forces at joints B, C, and D as shown in the figure below. The forces have magnitudes Fi 30 kip. F-15 kip, and F-5 kip. The truss is held in equilibrium by a pin at point A and a roller at point E. Note that sides ABC, CDE, AFD, and BFE are straight lines, and member CF is vertical. Joint F lies s 30 ft to the right and h=10 ft above joint A, and joint C lies h 10 ft above joint F. Use the method of joints to determine the force in each member of the truss, and indicate whether they are in tension or compression. Note: Express tension forces as positive (+) and compression forces as negative (-).
