Sample questions

1. 1.What is the magnitude of the moment of force when the perpendicular distance from the axis of rotation is zero?
   • A.Zero
   • B.Equal to the applied force
   • C.Infinite
   • D.Half the applied force
2. 2.In the diagram below, a spanner is used to loosen a tight nut. Why is a spanner with a longer handle more effective for this task?
   • A.A longer handle increases the perpendicular distance from the nut, producing greater torque for the same force.
   • B.A longer handle reduces the force needed to turn the nut by distributing it over a larger area.
   • C.A longer handle decreases the friction between the spanner and the nut, making it easier to turn.
   • D.A longer handle increases the mass of the spanner, which enhances its turning effect on the nut.
3. 3.When a boy weighing 20 kgf sits at one end of a 4 m long see-saw, it gets depressed at this end. How far from the centre, on the side opposite to the boy, should a man weighing 40 kgf sit to bring the see-saw to the horizontal position?
   • A.0.5 m
   • B.1 m
   • C.2 m
   • D.4 m
4. 4.A wheel is pivoted at its centre. A force of 20 N is applied tangentially at a point on its rim, 0.3 m from the centre. Calculate the moment of force produced.
5. 5.A scooter mechanic can open a nut by applying 120 N force using a lever of 50 cm. How long a handle is required if he wishes to open it by applying only 40 N?
   • A.1.5 m
   • B.0.5 m
   • C.1.0 m
   • D.2.0 m
