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.What is a single fixed pulley, and which of the following is a common use for it?
- A.A pulley with a movable axis, used to multiply force in lifting heavy loads.
- B.A pulley with a fixed axis, used to lift a water bucket from a well by changing effort direction.
- C.A pulley system combining fixed and movable pulleys, used to reduce effort significantly.
- D.A pulley with a fixed axis, used primarily to increase the speed of the load.
-
2.The correct relationship between the velocity ratio (V.R.) the distance through which effort act (d) and the distance through which load moves (D)
- A.V.R. × d = D
- B.V.R. = D × d
- C.V.R. × D = d
- D.none of these
-
3.The pulley system shown in the figure is used to raise a $650\,\mathrm{kg}$ load. What is the mechanical advantage and what force is exerted?
Efficiency = $75\%$ -
4.What is the defining characteristic of an ideal or perfect machine?
- A.It produces more energy than it consumes
- B.Its parts are weightless and frictionless, ensuring no energy loss
- C.It operates only under specific environmental conditions
- D.It requires no effort to produce work
-
5.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.
