ICSE Class 10 Machines — Mock Test (2027)
Free online mock test for Machines (ICSE Class 10 Physics) — 20 competency-based questions based on the latest CISCE 2027 syllabus, with instant marking. Try the samples below, then take the full test free.
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.A single fixed pulley is used because it
- A.has the mechanical advantage greater than 1
- B.has the velocity ratio less than 1
- C.gives 100% efficiency
- D.helps to apply the effort in a convenient direction
-
2.A single movable pulley has :
- A.velocity ratio 2 and actual mechanical advantage 2
- B.velocity ratio 2 and actual mechanical advantage more than 2
- C.velocity ratio 2 and actual mechanical advantage less than 2
- D.none of the above
-
3.What is meant by an ideal machine, and how does it differ from a practical machine?
- A.An ideal machine has 100% efficiency with no energy loss, while a practical machine loses energy due to factors like friction.
- B.An ideal machine produces more work output than input, while a practical machine has equal input and output work.
- C.An ideal machine is frictionless but has efficiency less than 100%, while a practical machine has no energy loss.
- D.An ideal machine and a practical machine both have 100% efficiency, but practical machines are more durable.

4.Assertion (A): A fishing rod is an example of a third-class lever. Reason (R): In a third-class lever, the effort is applied between the load and the fulcrum. (a) Both A and R are true, and R is the correct explanation of A. (b) Both A and R are true, but R is not the correct explanation of A. (c) A is true, but R is false. (d) A is false, but R is true.
- A.Both A and R are true, and R is the correct explanation of A.
- B.Both A and R are true, but R is not the correct explanation of A.
- C.A is true, but R is false.
- D.A is false, but R is true.

5.A fixed pulley is driven by a 100 kg mass falling at a rate of 8.0 m in 4.0 s. It lifts a load of 75.0 kgf. Calculate : (a) the power input to the pulley taking the force of gravity on 1 kg as 10 N. (b) the efficiency of the pulley, and (c) the height to which the load is raised in 4.0 s.
