magnitudes F₁ A scissors truss supports three forces at joints B, C, and D as shown in the figure below. The forces have 35 kip, F₂ = 10 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 s = 12 ft to the right and h = 4 ft above joint A, and joint C lies h = 4 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 (-). = A. HA B S F₁ F₂ 2 F C F3 D S E A h h
