Homework Statement
Figure P8.58 shows a claw hammer as it is being used to pull a nail out of a horizontal board. If a force of magnitude 150N is exerted horizontally as shown, find a) the force exerted by the hammer claws on the nail and b) the force exerted by the surface at the point of contact with the hammer head. Assume that the force the hammer exerts on the nail is parallel to the nail.
