Question

Specify whether the statements are true or false.

1. Moment of a force about a point is a free vector. [ Select ]
2. A force can be moved to any point along the line of action. [ Select ]
3. The magnitude of the equivalent resultant force of a distributed load can be calculated using the centriod of the load distribution area. [ Select ]
4. The resultant force of a couple force system is zero. [ Select ]
5. Moment axis is perpendicular to the plane containing both moment arm and force. [ Select ]

Answer 1

1. False

2. True

3. True

4. True

5. False

Step-by-step explanation:

Moment of a force is not a free vector. There are certain quantities along the line with which force is applied.

Force can be moved in any direction along the line of the action without changing the external reaction.

The magnitude of equivalent resultant force is distributed along the centroid point.

The resultant force of a couple force system is zero as it form opposite forces which balances off each other.
