What is moment of force(or) moment of couple
Answers
Answer:
couple and moment look similar but they are not. Major two differences between them.
The moment is produced by a single force and we need two forces to make a couple.
The moment may have a resultant force but the resultant force of a couple is zero.
A couple consist of two equal and opposite forces acting with two different but parallel line of action.
each force has its own moment.
moment of force depends 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 forces .
Moment of Force - Moment of force of a body is equal to the product of magnitude of the force applied and the perpendicular distance of the line of action of force from axis of rotation.
Moment of force = F x perpendicular distance.
Moment of Couple - Moment of Couple is equal to the product of either force applied and the perpendicular distance between two force / couple arm.
Moment of couple = Either force applied x couple arm.
