What is couple force in physics?

A couple is a pair of forces, equal in magnitude, oppositely directed, and displaced by perpendicular distance or moment. The simplest kind of couple consists of two equal and opposite forces whose lines of action do not coincide.

What is an example of a force couple?

A couple consists of two parallel forces that are equal in magnitude, opposite in sense and do not share a line of action. For example, the forces that two hands apply to turn a steering wheel are often (or should be) a couple. Each hand grips the wheel at points on opposite sides of the shaft.

What is a couple formula?

Couple Force Formula As we know, a couple is the combination of two parallel forces that have identical magnitude but opposite direction distinguished by a perpendicular distance. MC = r * F.

What is couple in mechanical engineering?

couple, in mechanics, pair of equal parallel forces that are opposite in direction. The turning effect, or moment, of a couple is measured by the product of the magnitude of either force and the perpendicular distance between the action lines of the forces.

What are characteristics of a couple force?

The main characteristics of a couple 1. The algebraic sum of the forces consisting the couple is zero. 2. The algebraic sum of the moment of the forces constituting the couple about any point is the same and equal to the moment of the couple itself.

What is couple force Class 11?

The couple is a pair of equal and opposite forces separated by a distance. We know that according to Newton’s third law of motion. Two equal and opposite forces will result in the mutual cancellation of the forces. The couple enables the rotational motion of a substance.
