A square metal plate $0\mathrm{.}180$ m on each side is pivoted about an axis through point O at its center and perpendicular to the plate. Calculate the net torque about this axis due to the three forces shown in the figre if the magnitudes of the forces are F$1=24$N $,$ F$2=15\mathrm{.}8$N $,$ and F$3=15\mathrm{.}8.$ The plate and all forces are shown in the plane of the page. Take positive torques to be counterclockwise
