The turning effect of a force, or torque or moment of force, depends on three main factors. First, the magnitude of the force is critical. A larger force generates a stronger turning effect, making it more effective in causing rotation. Second, the perpendicular distance from the axis of rotation to the point where the force is applied, known as the lever arm, plays a significant role. The farther the force is applied from the pivot point, the greater the torque. For example, pushing a door at its edge requires less effort than pushing it near the hinges because the distance from the pivot is larger. The third one is the angle at which force is applied. If the force should be applied to the lever at an angle that will ensure maximum turning effect, it would be perpendicular. If it applies at an angle, then just the perpendicular part of it has a role to play in creating rotation.
The turning effect of a force is known as torque or moment of force. This concept is essential to rotational motion and helps understand the proper working of levers, wrenches, and mechanical systems such as engines and turbines in applications.
