Expert Solution

Step 1: Introction

Torque is a measure of the force that can cause an object to rotate about an axis.

$\vec{τ} = \vec{r} \times \vec{F} τ = | r | | F | \sin θ . . . . . . . . . . . . . . . . . . . . . . . . . . . . (i)$

Where, $τ$ is the torque, r is the radius, F is the force and $θ$ is the angle between F and $θ$ is the angle between the force vector and the lever arm vector.
