1. What is the SI unit of force?
A. Joule
B. Newton
C. Pascal
D. Watt
Rationale: Force in SI units is defined as mass × acceleration.
Correct Answer: B. Newton
2. Which law states that pressure applied to a confined fluid is
transmitted equally in all directions?
A. Bernoulli’s Principle
B. Newton’s Second Law
C. Pascal’s Law
D. Hooke’s Law
Rationale: Pascal’s Law governs fluid pressure transmission.
Correct Answer: C. Pascal’s Law
,3. What is the derivative of displacement with respect to
time?
A. Acceleration
B. Velocity
C. Jerk
D. Momentum
Rationale: Velocity is the rate of change of displacement over
time.
Correct Answer: B. Velocity
4. The modulus of elasticity is defined as:
A. Stress/Strain
B. Strain/Stress
C. Force/Area
D. Energy/Volume
Rationale: Young’s modulus = stress divided by strain.
Correct Answer: A. Stress/Strain
5. What is the primary purpose of a retaining wall?
A. Increase drainage
