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.

Question

Item 9
A garage door is mounted on an overhead rail (Figure 1). The wheels at A and B have
rusted so that they do not roll, but rather slide along the track. The coefficient of kinetic
friction is 0.54. The distance between the wheels is 2.00 m, and each is 0.50 m from the
vertical sides of the door. The door is uniform and weighs 900 N. It is pushed to the left at
constant speed by a horizontal force F, that is applied as shown in the figure.

As shown below, a beam of length L is in equilibrium and is attached to a cable which is pulling it against a frictionless wall. The beam is not attached to the wall and the wall is only exerting a normal force on the beam. Additionally, there is a 702 N box hanging on a wire from the end of the beam. Determine the cable tension & the beam weight. 0.89 L 45° tension = beam weight = 702 N
