The moment of a force about a given axis depends on:

1. only on the magnitude of force
2. only on the perpendicular distance of force from the axis
3. neither the force nor the perpendicular distance of force from the axis
4. both, the force and its perpendicular distance from the axis.

For producing the maximum turning effect on a body by a given force, the perpendicular distance of the line of force from the axis of rotation should be :

1. minimum
2. it does not matter
3. maximum
4. zero

The moment of force for anticlockwise moment is taken as …………… and for clockwise moment is taken as ……………

1. positive, negative
2. negative, positive
3. positive, positive
4. negative, negative

The direction of rotation of a pivoted body can be changed by changing:

1. the direction of force
2. the point of application of force
3. both the direction of force and the point of application of force
4. the magnitude of force
