Question:

As shown in the figure below, a uniform beam is supported by a cable at one end and the force of friction at the other end. The cable makes an angle of θ = 30°,the length of the beam is L= 4.00 m, the coefficient of static friction between the wall and the beam is μs = 0.500, and the weight of the beam is represented by w. Determine the minimum distance x from point A at which an additional weight 2w (twice the weight of the rod) can be hung without causing the rod to slip at point A.

A wall has a horizontal beam attached to it a point labeled A. The beam extends to the right and the right end of the beam is labeled B, where a cable is attached at an angle theta. The cable runs up and left to attach to the wall above the beam. At a distance x away from the wall on the beam a rope hangs down with a mass labeled 2w on the bottom of the rope.
