A square metal plate 0.180 m on each side is pivoted about an axis through point 0 at its center and perpendicular to the plate (Fig. 10.39). Calculate the net torque about this axis due to the three forces shown in the figure if the magnitudes of the forces are F, = 18.0N, F, = 26.0N, and F, = 14.0N. The plate and all forces are in the plane of the page.
