Question

The point of action of force on a rigid body is:

• A. Fixed point on rigid body
• B. Fixed point but can be transferred anywhere along the line of action of force.
• C. Fixed point but can be transferred anywhere along the direction of force.
• D. Fixed point but can be transferred anywhere opposite to the direction of force.

Answer 1

The correct option is B

Fixed point but can be transferred anywhere along the line of action of force.

Definition of point of action of force:

The point on a rigid body where the force acts is called the point of action of force.

Definition of a rigid body:

A rigid body is a solid body in which, the deformation is zero or so small that it can be neglected.

Answer:

The point of action of force on a rigid body is a fixed point but can be transferred anywhere along the line of action of force.

Hence, option (b) is correct.
