Question

Prove that- Moment of couple = Force × couple arm.

Answer 1

hey !!

here is ur answer!!

Moment of force at the end A = F *OA ( anticlockwise)

Moment of force F at the end B = (Anticlockwise)

Total moment of couple ( moment of both the forces) = F * OA + F * OB
= F * ( OA + OB)

= F * d ( anticlockwise)

Therefore,

Moment of couple = force * couple arm...

Hope this helps u!!
