Sample questions

1. 1.Assuming the centre of gravity of a uniform rod is at its midpoint, how can the position of the centre of gravity of a triangular lamina be determined?
   • A.It is the intersection point of the medians (centroid) of the triangle.
   • B.It is the midpoint of the longest side of the triangle.
   • C.It is the average of the vertices' coordinates.
   • D.It is the point where the altitudes of the triangle meet.
2. 2.Which of the following is an example of a couple?
   • A.Pushing a box across the floor
   • B.Turning a water tap
   • C.Lifting a weight vertically upward
   • D.Pulling a rope tied to a fixed point
3. 3.A uniform metre rule is pivoted at its mid-point. A weight of $50\mathrm{gf}$ is suspended at one end of it. Where should a weight of $100\mathrm{gf}$ be suspended to keep the rule horizontal?
4. 4.Two forces each of magnitude $10\mathrm{N}$ act vertically upwards and downwards respectively at the two ends A and B of a uniform rod of length $4\mathrm{m}$ which is pivoted at its mid point O as shown in Fig. 1.29. Determine the magnitude of resultant moment of forces about the pivot O.
5. 5.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.
