Using a crowbar, a person can remove a nail by exerting little force, whereas pulling directly on the nail requires a large force to remove it (you probably can't). Why? Using a crowbar, a person can remove a nail by exerting little force, whereas pulling directly on the nail requires a large force to remove it (you probably can't). Why?
A.The applied force is at a large distance from the pivot, giving rise to a large torque.
B.The applied force is at a small distance from the pivot, giving rise to a large torque.
C.The applied force is at a large distance from the pivot, giving rise to a small torque.
D. Because the crowbar is heavy.
