11.52 ..* A claw hammer is Figure P11.52 used to pull a nail out of a board (Fig. P11.52). The nail is at an angle of 60° to the board, and a force F of magnitude 400 N applied to the nail is required to pull it from the board. The ham- F mer head contacts the board at 0.300 m point A, which is 0.080 m from where the nail enters the board. A horizontal force F, is applied to the hammer handle at a dis- -60° tance of 0.300 m above the board. What magnitude of force F, is required to apply the required 400-N force (F) to the nail? (You can ignore the weight of the hammer.) 0.080 m
