PLEASE EXPLAIN STEP BY STEP HOW YOU GOT THE ANSWER. I AM LEARNER .


A claw hammer is used to pull a nail out of a board. The nail is at an angle of 60? to the board, and a force F? 1 of magnitude 500 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 mfrom where the nail enters the board. A horizontal force F? 2 is applied to the hammer handle at a distance of 0.300 m above the board. (Figure 1)

Part A
What magnitude of force F? 2 is required to apply the required 500-N force (F1) to the nail? (You can ignore the weight of the hammer.)
Express your answer using two significant figures.

Explanation / Answer

Torque T about a point A

TA = 0

F2 * 0.3 = F1 * 0.08 * sin 60

F2 - 116 N
