1. A force of 200 N is applied at an angle of 30° above the horizontal.
What is the horizontal component of the force?
A. 100 N
B. 173 N
C. 200 N
D. 230 N
Answer: B
The horizontal component is F cos θ = 200 × cos 30° ≈ 173 N.
2. A rigid tank contains an ideal gas at constant volume. If the
absolute temperature doubles, what happens to the pressure?
A. It halves
B. It remains constant
C. It doubles
D. It quadruples
Answer: C
For an ideal gas at constant volume, pressure is directly
proportional to temperature.
3. The derivative of f(x) = 3x² − 4x + 7 is:
A. 6x − 4
B. 3x − 4
C. 6x + 4
D. x² − 4
Answer: A
Differentiate term by term: d/dx(3x²)=6x, d/dx(−4x)=−4.
,4. A beam is subjected to pure bending. Which stress is dominant?
A. Shear stress
B. Torsional stress
C. Normal stress
D. Bearing stress
Answer: C
Pure bending produces normal stresses varying linearly across the
section.
5. The SI unit of electric charge is:
A. Ampere
B. Volt
C. Coulomb
D. Ohm
Answer: C
Electric charge is measured in coulombs.
6. A process that occurs without heat transfer is called:
A. Isothermal
B. Adiabatic
C. Isobaric
D. Isochoric
Answer: B
Adiabatic processes have no heat exchange with surroundings.
7. Which material property measures resistance to elastic
deformation?
A. Toughness
B. Ductility
C. Young’s modulus
D. Hardness
, Answer: C
Young’s modulus relates stress to strain in the elastic range.
8. A pump increases the pressure of a fluid. The energy added per
unit weight is called:
A. Velocity head
B. Pressure head
C. Pump head
D. Elevation head
Answer: C
Pump head represents energy added to the fluid by the pump.
9. The Laplace transform of a constant K is:
A. K/s
B. Ks
C. s/K
D. K
Answer: A
The Laplace transform of a constant is K divided by s.
10. Which probability distribution is commonly used to model
time between events?
A. Normal
B. Binomial
C. Exponential
D. Poisson
Answer: C
The exponential distribution models interarrival times.
11. The area moment of inertia depends primarily on:
A. Material type
B. Shape of the cross-section
C. Length of the member
