Question

In the diagram alongside the moment of couple around point R is :

विकल्प

• 8 N-m in C.W.D.

• 8N-m in A.C.W.D.

• 6 N-m in C.W.D.

• 6 N-m in A.C.W.D.

Answer 1

8 N-m in C.W.D

Explanation:

The moment of a couple equals one force multiplied by the perpendicular distance between the forces: $$20\text{N} \times 0.40\text{m} = 8\text{N-m}$$. The forces in the diagram produce a clockwise turn.
