Question

prove that : moment of couple = force × couple arm​

Answer 1

Explanation:

sorry I don't know this answer

Answer 2

Answer:

At A and B. two equal and opposite forces, each of magnitude F is applied. The two forces rotate the bar in the anticlockwise direction. The perpendicular distance between the two forces is AB which is called the couple arm.

Moment of force F at the end A

=F×OA (anticlockwise)

Moment of force F at the end B

=F×OB (anticlockwise)

Total moment of a couple =F×OA=F×OB

=F×(OA+OB)=F=AB

=F×d (anticlockwise)

= Either force x perpendicular distance between the two forces (or couple arm)

Thus. Moment of couple = Force × Couple arm
