1. Which of the following is the SI unit of force?
A. Joule
B. Pascal
C. Newton
D. Watt
Rationale: Force in SI units is measured in Newtons (N), which is
kg·m/s².
2. The primary purpose of the factor of safety (FS) in design is to:
A. Reduce costs
B. Increase material strength
C. Ensure structural reliability under uncertainty
D. Minimize material usage
Rationale: FS accounts for uncertainties in loads, material properties,
and construction quality.
3. According to engineering ethics, a professional engineer must:
A. Maximize profits
B. Keep designs secret
C. Hold paramount the safety, health, and welfare of the public
,D. Delegate all responsibility to clients
Rationale: Public safety is the top priority in engineering ethics.
4. In a simply supported beam, maximum bending moment occurs:
A. At the supports
B. At midspan
C. At quarter points
D. Uniformly along the beam
Rationale: For a simply supported beam with a uniform load, the
bending moment is highest at midspan.
5. The continuity equation in fluid mechanics expresses:
A. Energy conservation
B. Mass conservation
C. Momentum conservation
D. Heat transfer
Rationale: The continuity equation ensures that mass entering a system
equals mass leaving.
6. The slope of the line tangent to a curve at a point is:
A. Area under the curve
B. Derivative of the function at that point
C. Integral of the function
D. Second derivative
Rationale: The derivative gives the instantaneous rate of change or
slope.
7. Which law states that the current through a conductor is
proportional to the voltage across it?
A. Newton’s Law
B. Faraday’s Law
, C. Ohm’s Law
D. Coulomb’s Law
Rationale: Ohm’s Law: V = IR.
8. In project management, PERT is used for:
A. Cost accounting
B. Scheduling and time estimation
C. Quality control
D. Material procurement
Rationale: PERT (Program Evaluation and Review Technique) estimates
project duration using probabilistic time analysis.
9. The Poisson’s ratio of a material is:
A. Ratio of stress to strain
B. Negative ratio of lateral strain to axial strain
C. Young’s modulus
D. Shear modulus
Rationale: Poisson’s ratio ν = -ε_lateral/ε_axial.
10. The unit of electrical resistance is:
A. Ampere
B. Volt
C. Ohm
D. Watt
Rationale: Resistance is measured in Ohms (Ω).
11. Bernoulli’s principle is based on the conservation of:
A. Mass
B. Temperature
C. Energy
D. Momentum
