If the torque required to loosen a nut on a wheel has a magnitude of 40.0 N·m and the force exerted by a mechanic is 133 N, how far from the nut must the mechanic apply the force?

The displacemnent of the nut will be 0.3 m.

Explanation:

As we know the torque () is given by

where is the displacement and is the applied force.

Given, and

So the magnitude of the displacement of the nut is given by

probably not if net force is zero
