1. Which of the following is a vector quantity?
A. Temperature
B. Mass
C. Velocity
D. Pressure
Rationale: Velocity has both magnitude and direction, making it a vector,
while temperature, mass, and pressure are scalars.
2. A beam is subjected to a uniform distributed load of 5 kN/m over a
span of 4 m. What is the total load on the beam?
, A. 4 kN
B. 5 kN
C. 20 kN
D. 9 kN
Rationale: Total load = w × L = 5 kN/m × 4 m = 20 kN.
3. Which of the following best describes Ohm’s Law?
A. Energy is conserved in a circuit
B. Voltage is proportional to current through a resistor
C. Current leads voltage in an inductor
D. Power is the product of current and resistance
Rationale: Ohm’s Law states that V = IR, showing proportionality between
voltage and current in a resistor.
4. For a fluid flowing in a pipe, the Reynolds number is calculated as Re =
ρVD/μ. What does Re > 4000 indicate?
A. Laminar flow
B. Transitional flow
C. Turbulent flow
D. Compressible flow
Rationale: A Reynolds number above 4000 indicates turbulent flow.
, 5. A 2 kg object accelerates at 3 m/s². What is the net force on the
object?
A. 2 N
B. 3 N
C. 5 N
D. 6 N
Rationale: Newton’s second law: F = m × a = 2 kg × 3 m/s² = 6 N.
6. Which of the following materials has the highest thermal conductivity?
A. Wood
B. Plastic
C. Copper
D. Air
Rationale: Metals like copper have very high thermal conductivity compared
to nonmetals.
7. The area under a stress-strain curve up to the elastic limit represents:
A. Tensile strength
B. Strain energy per unit volume
C. Modulus of elasticity
D. Yield strength
, Rationale: The area under the curve up to the elastic limit indicates energy
stored elastically.
8. Which gas law states that at constant temperature, pressure is
inversely proportional to volume?
A. Charles’s Law
B. Boyle’s Law
C. Avogadro’s Law
D. Dalton’s Law
Rationale: Boyle’s Law: P ∝ 1/V at constant temperature.
9. The probability of event A is 0.3, and event B is 0.5. If A and B are
independent, what is P(A and B)?
A. 0.8
B. 0.15
C. 0.5
D. 0.15
Rationale: For independent events: P(A ∩ B) = P(A) × P(B) = 0.3 × 0.5 = 0.15.
10. What is the pH of a solution with *H⁺+ = 1 × 10⁻³ M?
A. 3.5
B. 10
