A scissors truss supports three forces at joints B, C, and D as shown in the figure below. The forces have magnitudes F₁ = 5 kip, F₂ = 35 kip, and F3 = 25 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 8 = 15 ft to the right and h = 5 ft above joint A, and joint C lies h = 5 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.
