Couple
Easyphysics
Two equal and opposite forces of magnitude 5 N act on a body at a perpendicular distance of 0.6 m. What is the moment of the couple?
Select the correct option:
Solution
Incorrect! Answer:
3 N·m
- Definition: A couple is a pair of equal and opposite forces whose lines of action do not coincide. It produces torque without net linear force.
- Moment Calculation: M=Force×Perpendicular distance between forces.
- Substitute:
- M=5 N×0.6 m.
- Result: M=3 N·m.
- Note: The moment of a couple is the same about any point in its plane.
