001 10.0 points A shelf bracket is mounted on a vertical wall by a single screw. Neglect the weight of the bracket, and let s = 6.2 cm, $1 = 5.2 cm and $2 = 3.3 cm. Cal- culate the magnitude of the horizontal com- ponent of the force exerted on the bracket by the screw when a 33 N vertical force is ap- plied downward on the top (horizontal) por- tion of the backed a distance s from the wall, as shown in the diagram. Imagine that the bracket is slightly loose. Hint: use the bottom of the bracket as the origin of the torque
