- A cantilever truss supports three forces at joints along the top edge, as shown in the figure below. The forces have magnitudes F₁ = 7 kip, F₂ = 6 kip, and F3 = 9 kip. The truss is held in equilibrium by a pin at point A and a roller at point G. The lengths for members DE, EF, and FG is s = 6 ft and for member AG is h = 15 ft. Note that members BF and CE are vertical, and side ABCD is a straight line. The truss members are fabricated from low-carbon steel with a yield strength of Sy = ±32 ksi. Using the method of sections, determine the minimum cross sectional areas for members AB, BF, and EF so that each one exhibits a safety factor of SF = 2.1 with respect to yielding. - Note: Express tension forces as positive (+) and compression forces as negative (-).
