when does a body rotate when it is pivoted in a point??​

Answer 1

$\huge{\bold {\star {\fcolorbox {black} {yellow} {Answer}}}}$

• If the body is pivoted at a point and the force is applied on the body at a suitable point the body rotates about the axis passing through the pivot point. we can change the direction rotation by changing the point of application of force or by changing the direction of force.
