Question

Write the expression for the moment of force about a given axis.

Answer 1

The moment of force is as good as a torque.

$\overrightarrow{Torque}=\overrightarrow{r}\times \overrightarrow{F}$

The moment of a force F about any axis is the vector product of force and the perpendicular distance D, of the line of action of the force, from the axis under consideration.

$\overrightarrow{momentofforce}=\overrightarrow{r}\times \overrightarrow{F}$
