Question

the product of the force and perpendicular distance of the force from the pivoted point. i need one word answer plz ans this​

Answer 1

Explanation:

The turning effect of a force is known as the moment.

Answer 2

Answer:

$\boxed{\mathfrak{Moment \ of \ force / Torque}}$

Explanation:

• Rotational analogue of force is moment of force i.e. Torque.
• Torque is measured by the product of magnitude of force and perpendicular distance of the line of action of force from the axis of rotation.
• $\bf \overrightarrow{\tau} =\overrightarrow{r} \times \overrightarrow{F} = rF \: sin \theta. \hat{n}$
• The direction of $\rm \tau$ is perpendicular to the plane containing $\rm \overrightarrow{r}$ and $\rm \overrightarrow{F}$ and is given by right hand screw rule by rotating right hand screw from $\rm \overrightarrow{r}$ and $\rm \overrightarrow{F}$.
• SI unit of torque → N-m
• Dimensional formula of torque → $\rm \bold{[M^1L^2T^{-2}]}$
