Question

A body has a - 75.8 Nm moment of force, the body is describing a:

• A. clockwise motion
• B. anticlockwise moment
• C. linear motion
• D. curvilinear motion

Answer 1

The correct option is A

clockwise motion

Sign convention for moment of force:

1. The anticlockwise moment is taken as positive.
2. The clockwise moment is taken as negative.
3. - 75.8 Nm shows that there is a net clockwise moment present on the body therefore the body is in a clockwise motion.

Hence, option (A) is the correct answer.
