1. A steel rod has a length of 2 m and elongates by 1 mm under axial
loading. What is the normal strain in the rod?
A. 0.00025
B. 0.0005
C. 0.005
D. 0.05
Rationale: Normal strain equals change in length divided by original
length. Thus, strain = 0.001 m ÷ 2 m = 0.0005.
2. Which law states that the current through a conductor is directly
proportional to the voltage across it?
A. Kirchhoff’s Law
B. Faraday’s Law
,C. Ohm’s Law
D. Coulomb’s Law
Rationale: Ohm’s Law states that V = IR, meaning voltage is proportional
to current for a constant resistance.
3. What is the derivative of f(x) = 3x² + 2x − 5?
A. 6x² + 2
B. 6x + 2
C. 3x + 2
D. 6x − 5
Rationale: Using the power rule, the derivative of 3x² is 6x and the
derivative of 2x is 2. Constants differentiate to zero.
4. A pump increases the pressure of water in a pipe. What form of
energy is primarily added?
A. Thermal energy
B. Electrical energy
C. Mechanical energy
D. Chemical energy
Rationale: Pumps transfer mechanical energy to fluids, increasing pressure
and flow energy.
, 5. Which material property measures resistance to deformation under
load?
A. Density
B. Conductivity
C. Elastic modulus
D. Viscosity
Rationale: Elastic modulus, also called Young’s modulus, quantifies
stiffness and resistance to elastic deformation.
6. A simply supported beam carries a uniform load. Where is the
maximum bending moment located?
A. At the supports
B. Quarter span
C. Midspan
D. At the free end
Rationale: For a simply supported beam under uniform load, the maximum
bending moment occurs at the center of the span.
7. What is the SI unit of power?
A. Joule
B. Newton
, C. Volt
D. Watt
Rationale: Power is the rate of doing work and is measured in watts,
equivalent to joules per second.
8. In thermodynamics, what does an adiabatic process involve?
A. Constant pressure
B. Constant temperature
C. No heat transfer
D. No work transfer
Rationale: An adiabatic process occurs without heat exchange between the
system and surroundings.
9. Which statistical measure represents the average squared deviation
from the mean?
A. Median
B. Standard error
C. Variance
D. Correlation coefficient
Rationale: Variance measures the spread of data by averaging squared
deviations from the mean.
