Sample Tamil Nadu HSE First Year Basic Mechanical Engineering Practice Questions

Try these sample questions to review concepts for the Tamil Nadu HSE First Year Basic Mechanical Engineering exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which property of a metal describes its ability to be drawn into thin wire without fracture?
A.Hardness
B.Brittleness
C.Ductility
D.Toughness
Explanation: Ductility is the ability of a material to undergo plastic deformation under tensile load and be drawn into wire. Wire drawing depends on ductile behaviour of the metal.
2Cast iron is classified primarily as a:
A.Thermosetting plastic
B.Ceramic oxide
C.Ferrous metal
D.Non-ferrous metal
Explanation: Cast iron is an iron–carbon alloy and is therefore a ferrous metal. Non-ferrous metals do not have iron as the principal element.
3Which of the following is a non-ferrous metal commonly used for electrical conductors?
A.Mild steel
B.Grey cast iron
C.Copper
D.High-carbon steel
Explanation: Copper is a non-ferrous metal with high electrical conductivity and is widely used for wires and bus bars. Mild steel, cast iron, and high-carbon steel are iron-based (ferrous).
4The ability of a material to resist permanent deformation under an indenting load is called:
A.Elasticity
B.Plasticity
C.Hardness
D.Malleability
Explanation: Hardness is resistance to plastic indentation, scratching, or abrasion. Common hardness tests include Brinell, Rockwell, and Vickers.
5Mild steel typically contains carbon in approximately which range by weight?
A.0.60% to 1.00%
B.1.50% to 2.00%
C.0.05% to 0.30%
D.2.00% to 4.00%
Explanation: Mild (low-carbon) steel generally contains about 0.05% to 0.30% carbon. Higher carbon increases strength and hardness but reduces ductility and weldability. Cast irons usually have carbon above about 2%.
6Grey cast iron is preferred for machine tool beds mainly because of its:
A.High ductility and impact toughness
B.Excellent electrical conductivity
C.Good damping capacity and castability
D.Very high tensile strength relative to steel
Explanation: Grey cast iron has graphite flakes that give high damping of vibrations and good fluidity for casting complex shapes, making it ideal for machine beds and frames.
7Which alloying element is primarily added to steel to improve corrosion resistance in stainless steels?
A.Lead
B.Chromium
C.Sulphur
D.Phosphorus
Explanation: Stainless steels typically contain at least about 10.5–12% chromium, which forms a passive chromium-oxide film that resists corrosion.
8Aluminium is widely used in lightweight structures mainly because of its:
A.Very high density compared with steel
B.Low density and good corrosion resistance (oxide film)
C.Inability to be cast or extruded
D.Magnetic properties similar to pure iron
Explanation: Aluminium has low density (about 2.7 g/cm³) and forms a protective oxide film that resists atmospheric corrosion, making it suitable for lightweight structural and transport applications.
9The ability of a material to regain its original shape after removal of load (within the elastic limit) is called:
A.Plasticity
B.Elasticity
C.Brittleness
D.Creep
Explanation: Elasticity is reversible deformation: the material returns to its original dimensions when the load is removed, provided the elastic limit is not exceeded.
10Which of the following is a thermosetting plastic commonly used for electrical switchgear and moulded parts?
A.Polyethylene (PE)
B.Polyvinyl chloride (PVC) flexible film only
C.Bakelite (phenol-formaldehyde)
D.Natural rubber latex only
Explanation: Bakelite (phenol-formaldehyde) is a classic thermosetting plastic that hardens irreversibly on curing and is used for electrical insulators, switch bodies, and rigid moulded parts.

Tamil Nadu HSE First Year Basic Mechanical Engineering: Suggested Study Strategy

1Study from the current SCERT / Samacheer Kalvi Class 11 Basic Mechanical Engineering textbooks and the year's model question paper pattern.
2Practise both conceptual MCQs and the official long/short answer formats; this bank cannot replace writing or practical skill evidence.
3For calculation items (least count, cutting speed, heat, efficiency), rework numerical problems with units as in textbook examples.
4Complete workshop practicals and maintain records carefully — practical attendance is required for practical-bearing subjects.
5After each practice set, log weak topic areas by unit and re-read those textbook chapters before retesting.
