Question: a shelf bracket is mounted on a vertical wall by a single screw. Neglecting the weight of the bracket, and if s = 5.1 cm,

a shelf bracket is mounted on a vertical wall by a single screw. Neglecting the weight of the bracket, and if s = 5.1 cm, s1 = 4.1 cm and s2 = 2.2 cm, find the horizontal force component exerted on the bracket by the screw when a 95.4 N vertical force is applied as shown. Imagine that the bracket is slightly loose, meaning that there are two horizontal forces on the bracket, one from the screw, and one at the lowest point where it touches the wall. 1. 127.636 2. 73.0364 3. 124.091 4. 105.753 5. 39.8231 6. 146.667 7.96.8786 8. 118.668 9. 101.742 10. 83.6837 Answer in units of N
