1
Moment formula:
Answer & explanation
Correct: option B
M = F × d.
2
A 50 N force acts 0.4 m from a pivot. Moment?
Answer & explanation
Correct: option B
M = 50 × 0.4 = 20 N·m.
3
Principle of moments for balance:
Answer & explanation
Correct: option B
Clockwise = anticlockwise about any point.
4
Why are door handles placed far from the hinge?
Answer & explanation
Correct: option B
Larger d → larger turning moment for same push.
5
Gears multiply:
Answer & explanation
Correct: option C
Larger gear: more torque, slower rotation. Work conserved.
6
A see-saw: 50 N at 1.2 m left, 75 N right of pivot. For balance, distance right?
Answer & explanation
Correct: option A
50 × 1.2 = 75 × d → d = 60/75 = 0.8 m.
