Question

can a body be in equilibrium if it is revolving anti clockwise under the action of single torque​

Answer 1

No, the body cannot be in rotational equilibrium.

Reason:

• In order to attain rotational equilibrium a body must be under the influence of two opposite torques.

• Two opposite torques will lead to to cancellation of the Moments and results in rotational equilibrium.

• $\vec{\tau}=\vec{r}\times\vec{F}$

Lets see a diagram:

$\boxed{\setlength{\unitlength}{1cm}\begin{picture}(6,6)\put(3,3){\circle{1.4}}\put(3,3.7){\vector(-1,0){2}}\put(0.75,3.7){ F }\put(1,1){ \boxed{\sum(\tau)\neq 0} }\put(3,3){\line(0,1){0.7}}\put(3.25,3.15){r}\end{picture}}$

Here only one torque is present and is not equal to zero.

So , we can say that

$\boxed{ \therefore \: \sum \tau \: \neq \: 0}$

Hence , the body is not in rotational equilibrium.

Answer 2

Answer:

No.

Explanation:

The body will not be in equilibrium because second condition of equilibrium will not be fulfilled..Since single torque can never be zero and rotational acceleration will be produced..Therefore we can say that a body can not be in equilibrium under the action of single torque.
