The turning effect of force (or moment) refers to the ability of an object to resist changes in rotational motion about an axis of rotation when a net external force is applied to it. The magnitude of the turning effect of force is directly proportional to the magnitude of the applied force and inversely proportional to the distance from the axis of rotation at which the force is applied.
For example, consider a spinning wheel. When you exert a force on the wheel to increase its rotational velocity, the wheel resists this change because it wants to maintain its rotational motion. The magnitude of the turning effect of force is directly proportional to the magnitude of the applied force, which means that increasing the force will also increase the turning effect of force. The distance from the axis of rotation at which the force is applied also affects the turning effect of force. The closer the axis of rotation is to the point where the force is applied, the greater the turning effect of force.
The turning effect of force is a fundamental concept in physics that is used to explain many physical phenomena, such as the operation of various machines, the behavior of planets and other celestial bodies, and the design of structures such as bridges and towers
