Sample questions

1. 1.State one way to obtain a greater moment of a force about a given axis of rotation.
   • A.Increase the magnitude of the force applied.
   • B.Increase the perpendicular distance from the axis of rotation to the line of action of the force.
   • C.Apply the force parallel to the axis of rotation.
   • D.Decrease the angle between the force and the axis of rotation.
2. 2.A physical balance has its arms of length 60 cm and 40 cm. What weight kept on pan of longer arm will balance an object of weight 100 gf kept on other pan?
3. 3.On a see-saw, two children of masses $30\mathrm{kg}$ and $50\mathrm{kg}$ are sitting on one side of it at distances $2\mathrm{m}$ and $2.5\mathrm{m}$ respectively from its middle. Where should a man of mass $74\mathrm{kg}$ sit to balance it?
4. 4.What is meant by the term 'couple' in physics? State its effect and select the correct description from the options below.
   • A.Two equal and opposite parallel forces whose lines of action do not coincide, producing rotation.
   • B.Two forces acting in the same direction at different points, causing linear motion.
   • C.A single force applied at a point, resulting in both translation and rotation.
   • D.Two unequal forces acting in opposite directions, producing no net effect.
5. 5.A mechanic can open a nut by applying a force of 150 N while using a lever handle of length 40 cm. How long handle is required if he wants to open it by applying a force of only 50 N?
