Question

A nut is opened by a wrench of length 25 cm. If the least force required is 10 N, find the moment of force needed to turn the nut.

Answer

Required least force = 10N

r = 25cm = 0.25 m

We know the moment of force = F × r

Substituting the values of F and r we get,

Moment of force = 10 × 0.25 = 2.5 Nm

Hence, moment of force needed to turn the nut = 2.5 Nm
