A 4 kg cat sits on a 30 kg, 4 m long beam that is supported by a cable. She sits 0.5 m in from the right, and the cable is supporting the beam at a point 1 m in from the left.  The beam is free to rotate at the hinge.  What is the tension in the cable and horizontal and vertical forces exerted by the hinge?  What direction do the vertical and horizontal forces point?

Torque

Torque is the rotational equivalent of linear force in physics and mechanics. Based on the course of study, it is also known as the moment of force, rotational force, or turning effect.
