Sample Tamil Nadu HSE Second Year Basic Mechanical Engineering Practice Questions

Try these sample questions to review concepts for the Tamil Nadu HSE Second 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; ceramics and plastics are non-metallic.
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-speed 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-speed steel are iron-based (ferrous).
4The ability of a material to resist permanent deformation under a compressive or 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.
7Brass is an alloy of:
A.Copper and tin
B.Copper and nickel
C.Copper and zinc
D.Iron and chromium
Explanation: Brass is primarily a copper–zinc alloy. Bronze is typically copper–tin; cupronickel is copper–nickel; stainless steels are iron–chromium–nickel based.
8Annealing of steel is primarily done to:
A.Increase hardness and brittleness
B.Form a hard martensitic surface only
C.Relieve internal stresses and improve machinability/ductility
D.Increase carbon content of the bulk metal
Explanation: Annealing involves heating steel above a critical temperature and slow cooling to soften the metal, relieve residual stresses, refine grain structure, and improve ductility and machinability.
9In hardening of high-carbon steel, the heated part is usually cooled rapidly by:
A.Furnace cooling over many hours
B.Air cooling only in still air (normalising rate only)
C.Quenching in water, oil, or brine
D.Holding at room temperature without prior heating
Explanation: Hardening of steel involves austenitising and rapid quenching (commonly water, oil, or brine depending on section and grade) to form hard martensite.
10Temperatures for tempering hardened steel are generally chosen to:
A.Raise hardness to the maximum possible value
B.Melt the steel and recast it
C.Reduce brittleness and adjust toughness/hardness balance
D.Carburise the entire cross-section completely
Explanation: Tempering reheats hardened steel to a temperature below the lower critical range and cools it, reducing brittleness and residual stresses while trading some hardness for toughness.
