Question

What is the moment of force if a force of 6 N acts 1.5 m from a pivot? ​

Answer 1

moment of force is a vector that is by definition is a cross

Answer 2

Force of 6N acts at 1.5 metres from a pivot.

• So, the pivot acts an the axis.

• And moment of force refers to TORQUE applied by the force.

Let torque be $\tau$.

$\tau = force \times ( \perp distance \: from \: axis)$

$\implies \tau = 6 \times 1.5$

$\implies \tau = 9 \: Nm$

So, moment of force (or torque) is 9 Nm.
