Question

Which of the following statements is true about moment of force(torque)?

• A. Torque is independent of the distance of the force from the pivot.
• B. Torque depends on the perpendicular distance of force from the pivot.
• C. Torque and force have the same units.
• D. Torque is measured in the units of newton.

Answer 1

The correct option is B Torque depends on the perpendicular distance of force from the pivot.

Torque or moment of force is given by the formula:
Torque = Force $\times$ Perpendicular distance from the pivot

So, larger the distance from the pivot, larger is the torque.

Torque is generally measured in the units of newton metre (N-m) whereas force is measured in the units of newton (N).
