Sample Maharashtra HSC Mechanical Maintenance (Bifocal) Practice Questions

Try these sample questions to test your Maharashtra HSC Mechanical Maintenance (Bifocal) exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1In a mechanical workshop, a try square is primarily used to:
A.Measure large shaft diameters to 0.01 mm
B.Check right angles and mark lines square to an edge
C.Cut internal threads in a drilled hole
D.Measure fluid pressure in a pump delivery line
Explanation: A try square checks and marks 90° relationships between faces and edges during layout and fitting work.
2A hacksaw blade with a higher teeth-per-inch (TPI) count is generally preferred for:
A.Cutting thick soft timber only
B.Cutting thin metal sections and hard materials with finer teeth
C.Rough-cutting large wooden beams only
D.Measuring thread pitch on bolts
Explanation: Finer blades (higher TPI) suit thinner stock and harder metals for cleaner cuts; coarser blades suit thicker softer sections.
3Before using a steel rule for accurate layout, the fitter should first:
A.Oil the rule heavily so numbers smear
B.Ensure the zero end and edge are clean and undamaged
C.Heat the rule until red hot
D.Bend the rule to match curved work
Explanation: Accurate measurement needs a clean, undamaged zero end and straight edge; damaged tips introduce error.
4A centre punch is mainly used to:
A.Tighten pipe unions without marring chrome
B.Mark a starting point for drilling so the drill does not walk
C.Measure internal diameter of a bush
D.Cut external threads on a pipe
Explanation: Centre punching creates a small conical indent that guides the drill point and reduces wander.
5Which instrument is most appropriate for measuring a shaft diameter to about 0.01 mm in a fitting shop?
A.Ordinary metre tape only
B.Outside micrometer (or vernier caliper of suitable resolution)
C.Spirit level only
D.Pipe wrench
Explanation: Outside micrometers and suitable vernier calipers provide the precision needed for shaft diameters in fitting work.
6Vee blocks are commonly used with a surface plate to:
A.Heat-treat steel by packing in carbon
B.Support and locate cylindrical work for marking or inspection
C.Thread PVC pipes with heat only
D.Prime a centrifugal pump
Explanation: Vee blocks cradle round stock so centres and features can be marked or checked square/parallel on a surface plate.
7A dial indicator (dial gauge) in machine maintenance is most often used to:
A.Cut metric internal threads
B.Check run-out, alignment, and small linear deviations
C.Measure cutting fluid pH only
D.Replace the function of PPE
Explanation: Dial indicators magnify small displacements for alignment, run-out, and comparative measurement during setup and maintenance.
8Files are classified partly by cut (single/double) and by grade such as rough, bastard, second-cut, and smooth. A smooth file is best for:
A.Removing large amounts of metal rapidly on a casting
B.Finishing and producing a finer surface after coarser filing
C.Cutting wood joints only
D.Softening steel by annealing
Explanation: Smooth files have finer teeth for finishing after rough and intermediate stock removal.
9A feeler gauge set is used to:
A.Measure small clearances/gaps between mating parts
B.Tighten foundation bolts to design torque only
C.Cut cast-iron pipe with a chain cutter only
D.Test insulation resistance like a megger
Explanation: Feeler gauges are thin leaves of known thickness for checking clearances (valves, bearings, assemblies).
10When storing precision measuring instruments such as micrometers, good practice includes:
A.Leaving them clamped tightly on the largest reading overnight
B.Cleaning, oiling lightly if required, and storing in a protective case free from dust and shocks
C.Dropping them into a coolant sump for corrosion protection
D.Using them as hammers when a soft face is needed
Explanation: Precision tools need cleaning, light protection from rust, and protected storage to keep accuracy.
