CLEAR YOUR CONCEPT:- What is the difference between Moment and Couple? • Moment of force is the measure of turning effect of a force about a point. A couple consists of two equal and opposite forces acting with two different but parallel lines of action. Each force has its own moment. • Moment of a force is dependent on the distance from the pivot and the magnitude of the force while the moment of a couple is the net effect of the two moments of the forces. Moment of a couple is independent of the location of the point considered. It is constant throughout the plane. The resultant moment of a couple is called a torque. • Torque, also called moment or moment of force, is the tendency of a force to rotate an object about an axis, fulcrum, or pivot. Just as a force is a push or a pull, a torque can be thought of as a twist. Couple - Two equal but opposite forces Torque - Moment of a couple For more updates join Mechanical Engineers Rocks.
