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.Which of the following expressions correctly represents the mechanical advantage (M.A.) of an inclined plane in terms of its length (L) and height (h)?
- A.M.A. = h / L
- B.M.A. = L * h
- C.M.A. = L / h
- D.M.A. = (L + h) / L
-
2.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
-
3.Which two factors are primarily responsible for the efficiency of a pulley system being less than 100 percent?
- A.Friction between the string and pulleys, and the weight of the movable block.
- B.Air resistance and the length of the string used.
- C.The color of the pulleys and the material of the string.
- D.The angle of the string and the speed of lifting.
-
4.Load is
- A.resistive force to be overcome by machine
- B.exerted by machine
- C.external agency supplied to the machine
- D.none of the above
-
5.The adjacent Fig. 3.27 shows a fixed pulley used by a boy to lift a load of $400\,\mathrm{N}$ through a vertical height of $5\,\mathrm{m}$. Calculate the work done by the boy and the work done on the load. Assume the pulley is ideal.
