A force of 5N act at a point Y on a rod XYZ as shown in the diagram above, if XY is 2m. What is the moment of the force about point X?
-
0Nm
- 3Nm
- 7Nm
- 10Nm
The correct answer is: A
Explanation
X is in the line of action of the force, Therefore moment is equal to zero.
Moment = force x perpendicular distance. ( x is horizontal distance, not perpendicular distance)
