# Lesson Worksheet: Moment of a Force about a Point in 2D: Vectors Mathematics

In this worksheet, we will practice finding the moment of a planar system of forces acting on a body about a point as a vector.

**Q5: **

The force is acting on the point . Given that and , determine the moment of this force about both points and .

- A,
- B,
- C,
- D,
- E,

Which of the following would you conclude about the line of action of the force ?

- AThe line of action of passes through the point .
- BThe line of action of bisects .
- CThe line of action of is parallel to .
- DNone of the answers are correct.

**Q6: **

Given that , , and are acting on the point , determine the moment of the resultant of these forces about the two points and .

- A,
- B,
- C,
- D,
- E,

Which of the following would we conclude about the line of action of the resultant force?

- AThe line of action of the resultant force passes through both points and .
- BThe line of action of the resultant force is parallel to .
- CThe line of action of the resultant force passes through point .
- DThe line of action of the resultant force bisects .
