Who sits the March 2026 HSE+1 public exam?

The official March 2026 HSE+1 public examination timetable on dge.tn.gov.in is issued for arrear candidates (typically 2018–2025) as notified; regular school candidates follow the current DGE session rules and school calendar. Confirm your candidate category on the DGE site.

How long is the official theory paper?

Theory sittings are typically scheduled from 10:00 a.m. to 1:15 p.m., including question-paper reading and candidate particulars verification before the main writing period.

What is the passing score?

Minimum 35 out of 100 per subject overall under the HSE pattern (HSE_E.pdf), with additional floors such as theory minimum 15/70 and required practical appearance for practical-bearing subjects. Confirm the current DGE result rules for your candidate category.

Is this practice bank the same format as the official paper?

No. Official papers use mixed written formats (and practicals where applicable). These 100 questions are an English-language multiple-choice study adaptation for knowledge and calculation practice only.

Where can I find the official timetable and scheme?

Download the public examination timetable and HSE scheme documents from the Directorate of Government Examinations website (dge.tn.gov.in), including the March 2026 HSE timetable PDF.

Sample Tamil Nadu HSE First Year Basic Mechanical Engineering Practice Questions

Try these sample questions to test your Tamil Nadu HSE First Year Basic Mechanical Engineering exam readiness. 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.
