find the force exerted by the hammer claws on the nail. (Assume that the force the hammer exerts on the nail is parallel to the nail). Answer in units of N.

Question

The figure shows a claw hammer as it pulls a nail out of a horizontal board if a force of magnitude 165 N is exerted horizontally as shown, find the force exerted by the hammer claws on the nail. (Assume that the force the hammer exerts on the nail is parallel to the nail). Answer in units of N.

Answer 1

Answer:

When you are pulling nail out using hammer the force situation is described as follows.

 Direction/magnitude of force on hammer handle

 <=========== 165 N

This is the force applied to nail from claw. Assume rigid contact between claw and the surface of the nail.

Direction/magnitude of reaction force of nail on claw

============> 165 N

I hope this helps.
