Sample questions

1. 1.A body is pivoted at a point. A force of 10 N is applied at a distance of 30 cm from the pivot. What is the moment of force about the pivot?
   • A.0.3 Nm
   • B.3 Nm
   • C.30 Nm
   • D.300 Nm
2. 2.A mechanic can open a nut by applying a force of 150 N while using a lever handle of length 40 cm. What length of handle, in metres, is required if he wants to open the same nut by applying a force of only 50 N?
   • A.0.4 m
   • B.1.2 m
   • C.3.0 m
   • D.0.133 m
3. 3.A nut is opened by a wrench of length $20\mathrm{cm}$. If the least force required is $2\mathrm{N}$, find the moment of force needed to loosen the nut.
4. 4.Which of the following quantity remains constant in a uniform circular motion
   • A.velocity
   • B.speed
   • C.acceleration
   • D.both velocity and speed
5. 5.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.
