Engineer Intern Exam Questions 1–20

1. Which of the following are fundamental properties of materials used in civil
engineering?
A) Strength
B) Ductility
C) Color
D) Thermal conductivity

Correct: A, B, D
Rationale: Strength, ductility, and thermal conductivity are key material properties affecting
performance. Color is generally aesthetic and not a fundamental property.

2. What is the primary function of a load-bearing wall in a structure?
A) Support weight from above
B) Provide insulation
C) Act as a partition
D) Enhance aesthetic appeal

Correct: A
Rationale: Load-bearing walls carry structural loads from floors and roofs above, unlike
partitions which only divide space.

3. Which of the following are common types of engineering drawings?
A) Schematic diagrams
B) Flowcharts
C) Blueprints
D) Pictograms

Correct: A, C
Rationale: Schematic diagrams and blueprints are standard in engineering design
documentation. Flowcharts and pictograms are not used for structural or mechanical designs.

4. In electrical circuits, Ohm’s Law states that:
A) V = IR
B) I = VR

,C) P = VI²
D) R = VI

Correct: A
Rationale: Ohm’s Law defines the relationship between voltage (V), current (I), and resistance
(R) as V = IR.

5. Which of the following are considered renewable energy sources?
A) Solar
B) Wind
C) Coal
D) Biomass

Correct: A, B, D
Rationale: Solar, wind, and biomass are renewable; coal is a non-renewable fossil fuel.

6. Which software tools are commonly used in engineering design?
A) AutoCAD
B) MATLAB
C) Adobe Photoshop
D) SolidWorks

Correct: A, B, D
Rationale: AutoCAD and SolidWorks are used for design drafting, MATLAB for simulation.
Photoshop is for graphics, not engineering design.

7. The bending moment in a simply supported beam is maximum at:
A) Supports
B) Midspan
C) Quarter span
D) Third points

Correct: B
Rationale: For a simply supported beam with a central point load, the maximum bending
moment occurs at the midspan.

8. Which of the following are types of bridges based on structure?
A) Suspension
B) Arch
C) Cantilever
D) Tunnel

Correct: A, B, C
Rationale: Suspension, arch, and cantilever are bridge types. Tunnel is an underground passage,
not a bridge.

, 9. In thermodynamics, which of the following are state variables?
A) Pressure
B) Temperature
C) Volume
D) Heat

Correct: A, B, C
Rationale: State variables describe the state of a system. Heat is a process quantity, not a state
variable.

10. Which of the following engineering disciplines primarily deals with the design of
machinery?
A) Mechanical engineering
B) Civil engineering
C) Electrical engineering
D) Industrial engineering

Correct: A
Rationale: Mechanical engineering focuses on machinery and mechanical systems design.

11. Which of the following factors influence the compressive strength of concrete?
A) Water-cement ratio
B) Aggregate type
C) Ambient temperature
D) Reinforcement type

Correct: A, B, C
Rationale: Water-cement ratio, aggregate, and temperature affect concrete curing and strength.
Reinforcement affects tensile, not compressive strength.

12. Which of the following are methods of heat transfer?
A) Conduction
B) Convection
C) Radiation
D) Reflection

Correct: A, B, C
Rationale: Heat transfers via conduction, convection, and radiation. Reflection is a property of
light, not heat transfer.

13. Which of the following are advantages of using CAD in engineering?
A) Reduces design time
B) Improves accuracy
C) Eliminates need for prototypes
D) Facilitates simulation
