Concept explainers

Torque

Torque is the rotational equivalent of linear force in physics and mechanics. Based on the course of study, it is also known as the moment of force, rotational force, or turning effect.

Question

What is the mechanical advantage of a nail puller—similar to the one shown in Figure shown —where you exert a force 45 cm from the pivot and the nail is 1.8 cm on the other side? What minimum force must you exert to apply a force of 1250 N to the nail?What force does the nail puller exert on the supporting surface? The nail puller has a mass of 2.10 kg.
