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 machine is driven by a 100 kg mass that falls 8.0 m in 4.0 s. It lifts a load of mass 500 kg vertically upwards. Taking g = 10 ms⁻², calculate: (a) the force exerted by the falling mass, (b) the work done by the falling mass in its displacement by 8.0 m, (c) the power input to the machine, (d) the power output of the machine if its efficiency is 60%, and (e) the work done by the machine in 4.0 s.

2.A single fixed pulley is used because :
- A.it multiplies effort
- B.it multiplies speed
- C.its efficiency is $100\%$
- D.it changes the direction of applied effort
-
3.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
-
4.Define a machine and select the option that correctly states its four main functions.
- A.A device that overcomes a large resistive force by applying a small force, with functions: (1) force multiplier, (2) changes point of effort, (3) changes direction of effort, (4) gains speed.
- B.A tool that increases energy output, with functions: (1) generates power, (2) reduces friction, (3) amplifies motion, (4) converts energy forms.
- C.A mechanism that only changes the direction of force, with functions: (1) reverses effort, (2) balances loads, (3) stabilizes motion, (4) minimizes effort.
- D.A device that solely multiplies speed, with functions: (1) accelerates objects, (2) increases distance, (3) reduces time, (4) optimizes efficiency.

5.Assertion (A): A pair of pliers 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.
