Here is the answer to Question 2 (a).

Question 2 (a): What is meant by moment of a force?

The moment of a force, also known as torque, is the turning effect produced by a force about a pivot point or axis. It is calculated as the product of the force's magnitude and the perpendicular distance from the pivot to the line of action of the force. The unit of moment is Newton-meter ($\text{N} \cdot \text{m}$).

$\boxed{\text{Moment of a force is the turning effect produced by a force about a pivot point.}}$
