Jane is holding a bar by applying a vertical force at the point shown. The bar is stationary, 1 m, 10 kg, and at angle 20, and can rotate about O. If the bar's center of mass is at its middle, calculate the magnitude and direction of vertical force at the hinge at O. 0.3 m 00= 20 83.2 N, downward 83.2 N, upward 65.4 N, upward 65.4 N. downward
