Question

State one way to reduce and maximize the moment of force about given axis of rotation​

Answer 1

Answer:

By increasing and decreasing the radius you can get it .

For eg : if the radius is large from the axis of rotation the moi will be more and so the rotations will be less due to more resistance and Omega i.e. angular velocity will be more

But if radius low so moi less

Explanation:

Take an example of a man roller skating on ice he tends to close his arms when He wants the speed to increase.

Omega is inversely prop to moi

Answer 2

Moment of force depends on the distance of line of action of the force from the axis of rotation. Decreasing the perpendicular distance from the axis reduces the moment of a given force.
