What to expect: This mock test covers key concepts from the Machines chapter — including application-based and competency-focused questions aligned with how ICSE actually sets the paper.
Tip: Attempt without notes first to identify gaps, then review explanations for any wrong answers. Retake after a few days for best retention.
Sample questions
-
1.Which of the following correctly expresses the relationship between mechanical advantage (M.A.), velocity ratio (V.R.), and efficiency (η) of a machine?
- A.M.A. = η × V.R.
- B.V.R. = η × M.A.
- C.η = M.A. + V.R.
- D.M.A. = η / V.R.
-
2.What is the efficiency of an ideal single movable pulley?
- A.50% because the load is shared between two segments of the rope.
- B.100% because the mechanical advantage equals the velocity ratio.
- C.75% due to frictional losses in the pulley system.
- D.200% because the velocity ratio is double the mechanical advantage.
-
3.Which of the following best defines an inclined plane?
- A.A wheel and axle system
- B.A plank kept at an inclination to the ground acting as a force multiplier
- C.A lever with the fulcrum at the center
- D.A pulley system with multiple wheels
-
4.Refer to Fig. 3.1 (c) showing a Class III lever. If the effort arm is 2.5 cm and the load arm is 10.0 cm, calculate the mechanical advantage (M.A.) of the lever in the ideal case. If the efficiency of the lever is 60%, what is the actual M.A.?
-
5.Which of the following correctly expresses the velocity ratio (V.R.) of a machine mathematically?
- A.V.R. = d_L / d_E
- B.V.R. = v_L / v_E
- C.V.R. = d_E / d_L
- D.V.R. = (d_E + d_L) / d_L
