Stationary l 302-m board of mass 456 kg is hinged at one, Ask an Expert

Academics

stationary L = 3.02-m board of mass 4.56 kg is hinged at one end. A force F is applied vertically at the other end, and the board makes a ? = 31.4° angle with the horizontal. An m = 60.0-kg block rests on the board x = 83.3 cm from the hinge, as shown in the figure below.

Calculate the magnitude of the force F.

Calculate the force exerted by the hinge.

Calculate the magnitude of the force F exerted by the hinge, if F is exerted, instead, at right angles to the board.
