Question

(B) The torque $	au$ is given by the formula $	au = \vec{r} 	imes \vec{F}$,where $\vec{r}$ is the position vector from the axis of rotation (hinge)

Vedclass · Accepted Answer

To increase the torque for a given force.

Vedclass · Answer

(B) The torque $	au$ is given by the formula $	au = \vec{r} 	imes \vec{F}$,where $\vec{r}$ is the position vector from the axis of rotation (hinge) to the point where the force $\vec{F}$ is applied.By placing the handle at the end opposite to the hinges,the distance $r$ is maximized.Since $	au = rF \sin 	heta$,increasing $r$ results in a larger torque for the same amount of applied force.This makes it easier to open or close the door or window with minimal effort.

Why is the handle of a door or window placed at the end opposite to the hinged side?

Find the torque about the origin when a force of $3 \hat{j} \text{ N}$ acts on a particle whose position vector is $2 \hat{k} \text{ m}$.

The torque of a force $\overrightarrow{F} = -3\hat{i} + \hat{j} + 5\hat{k}$ acting at the point $\overrightarrow{r} = 7\hat{i} + 3\hat{j} + \hat{k}$ is:

The position vectors of two particles of a rigid body are $(3, 0, 0) \ m$ and $(0, 3, 0) \ m$. Forces of $(0, 1, 0) \ N$ and $(0, -1, 0) \ N$ act on these particles respectively. The torque of the couple is ....... $Nm$.

Show that the moment of a couple does not depend on the point about which you take the moments.
