Solution
Moment of force:
Moment of force is the tendency of force that causes a body to rotate about a specific axis. The momentum of force is the product of force and perpendicular distance from the line of the action.
The measurement of the turning effect is known as torque .
Mathematically, it can be represented as , where is the force applied and is the distance from the fixed axis.
An illustrative diagram of the moment of force is given below.
Unit of the moment of force:
The SI unit of moment of force is Newton-meters .
In the CGS system, the unit of moment of force is dyne-centimeter .
