1. A long wooden rod is mounted on an axle that goes through its center of mass as shown in the figure below. A 200 N force is applied at its left end as shown. What force F must be exerted at the other end in order for the rod to not spin? A. 50 N B. 100 N C. 200 N D. 400 N 200 N F =? E. 800 N 2. Suppose that instead, the force is applied halfway from the end as shown. What force F would be required to keep the board in equilibrium? A. 50 N B. 100 N C. 200 N D. 400 N 200 N F =? E. 800 N 3. Suppose that instead, the force is applied on quarter from the end as shown. What force F would be required to keep the board in equilibrium? A. 50 N B. 100 N C. 200 N D. 400 N 200 N F =? E. 800 N
