Question

The diagrams below show a force F = 40 N acting on a rod AB pivoted at A in different directions. Identify the correct statement.

विकल्प

• P and S have opposite moments.

• The magnitude of the moment of force is maximum in R.

• The magnitude of the moment of force is maximum in P and Q.

• The moment of force in R is negative.

Answer 1

The magnitude of the moment of force is maximum in R.

Explanation:

The magnitude of the moment is greatest when the force acts perpendicular to the rod. In diagram R, the force has this direction, so its moment is maximum. The other statements do not match the directions and turning effects shown.
