11.48 … A claw hammer is used to pull a nail out of a board (Fig. P11.48). The nail is at an angle of 60_ to the board and a force F S 1 of magnitude 400 N applied to the nail is required to pull it from the board. The hammer head contacts the board at point A which is 0.080 m from where the nail enters the board. A horizontal force F S 2 is applied to the hammer handle at a distance of 0.300 m above the board. What magnitude of force F S 2 is required to apply the required 400-N force 1F12 to the nail? (Ignore the weight of the hammer.)

I have not created a lesson for this question yet.

Please leave a comment below with specifics about the question, and I will make a detailed lesson on it as soon as possible. (I can usually have something up within a day.)

NEED IMMEDIATE HELP? Get the student solution manual here: University Physics Manual otherwise, I should be able to get a video lesson up within a day or so.
