Question

For producing the maximum turning effect ona body by a given force, the perpendicular distance of the line of action of force from the axis of rotation should be ______.

Options

• minimum

• it does not matter

• maximum

• zero

Answer 1

For producing the maximum turning effect ona body by a given force, the perpendicular distance of the line of action of force from the axis of rotation should be maximum.

Explanation:

The turning effect of a force (moment of force) depends on the perpendicular distance from the axis of rotation. Greater the perpendicular distance, greater is the turning effect of the force.
