Question

Door hinge is about 1.5 m away from handle, and a boy applies a force of 4 n. moment of force will be

Answer 1

Moment of force is torque hence T=F*r

=1.5*4

=6Nm

Answer 2

Moment = Force × Perpendicular distance from the pivot.

Since force is measured in newtons (N) and distances in metres (m) the unit for a moment is the newton-metre (Nm).

M = F × d

M = 4 × 1.5

= 6 Nm
