A simple truss supports a force Fat joint A, as shown in the figure below. The force has a magnitude F and is inclined by an angle = 35° from the horizontal. The lengths for all horizontal members is s = 7 m and for all vertical members is h = 7 m. The truss is held in equilibrium by a pin at point E and a roller at point F. Using the method of joints, determine the largest applied force Fmax so that the force in each truss member does not exceed ±100 kN. Note: Express tension forces as positive (+) and compression forces as negative (-).
