Principle of Moment MCQ (Multiple Choice Questions) PDF Download

As we have learnt that Moment of force is F × d, so the formula for weight in relevance to moment of force will be

1. mg × d
2. mg/d
3. mg + d
4. mg - d

Correct condition for state of equilibrium in principle of moment is

1. distance between the two objects in beam balance should be same
2. resultant force should be zero
3. the weight of both objects on the beam balance should be same
4. the tension should be equal on both sides

2. 8 N
3. 14 N
4. 18 N

Moment of force applied on a door is 15 N m and force applied is 3.75 N, distance of handle from pivot is

2. 18.75 m
3. 4 m
4. 45 m

Door hinge is about 1.5 m away from handle, and a boy applies a force of 4 N. moment of force will be

1. 5.5 N m
