A horizontal 14.9 kg beam 2.1 m long is attached to the wall by a hinge at its left end.

A horizontal   14.9 kg beam 2.1 m long is attached to the wall by a hinge at its left end. A cable is connected from the right end of the beam to the wall, at an angle of  27 ° above the beam, as shown below. A 55 kg sign is hung  1.6 m from the left end of the beam.

Part A - Find the tension in the cable.

Part B - Find the horizontal force exerted on the wall by the hinge.

Part C - Find the vertical force exerted on the wall by the hinge.

Use a negative sign if the force is downward, and a positive sign if the force is upward.
