1. Which organization is primarily responsible for regulating
professional engineering licensure in Louisiana?
A. Louisiana Department of Education B. Louisiana Professional
Engineering and Land Surveying Board C. Louisiana Department
of Transportation and Development D. National Institute of
Standards and Technology
Correct answer: B. Louisiana Professional Engineering and
Land Surveying Board
Rationale: The Louisiana Professional Engineering and Land
Surveying Board oversees professional engineering licensure
and regulates the practice of engineering under state law.
2. What is the primary purpose of the Fundamentals of
Engineering (FE) examination?
A. To test advanced project management only B. To establish
eligibility for contractor registration C. To assess foundational
engineering knowledge D. To replace all professional
experience requirements
Correct answer: C. To assess foundational engineering
knowledge
,Rationale: The FE exam assesses fundamental engineering
knowledge and is a common step toward professional engineer
licensure.
3. What is the SI unit of force?
A. Joule B. Newton C. Watt D. Pascal
Correct answer: B. Newton
Rationale: Force is measured in newtons (N), equivalent to one
kilogram-meter per second squared.
4. Which equation represents Newton’s second law of
motion?
A. F=maF=ma B. P=VIP=VI C. V=IRV=IR D. W=mg2W=mg2
Correct answer: A. F=maF=ma
Rationale: Newton’s second law states that the net force on an
object equals its mass multiplied by its acceleration.
5. What is the derivative of x3x3 with respect to xx?
A. x2x2 B. 2x2x C. 3x23x2 D. 3x33x3
Correct answer: C. 3x23x2
Rationale: Applying the power rule,
d(xn)/dx=nxn−1d(xn)/dx=nxn−1, gives 3x23x2.
6. What is the area of a circle with a radius of 4 m?
A. 8π m28π m2 B. 12π m212π m2 C. 16π m216π m2 D.
32π m232π m2
,Correct answer: C. 16π m216π m2
Rationale: The area is
A=πr2=π(4)2=16π m2A=πr2=π(4)2=16π m2, approximately
50.27 square meters.
7. What is the approximate acceleration due to gravity near
Earth's surface?
A. 4.9 m/s24.9 m/s2 B. 9.81 m/s29.81 m/s2 C.
15.2 m/s215.2 m/s2 D. 32.2 m/s232.2 m/s2
Correct answer: B. 9.81 m/s29.81 m/s2
Rationale: Standard gravitational acceleration near Earth's
surface is approximately 9.81 m/s29.81 m/s2.
8. What does the slope of a position-versus-time graph
represent?
A. Acceleration B. Force C. Velocity D. Momentum
Correct answer: C. Velocity
Rationale: The slope gives the rate of change of position with
time, which is velocity.
9. What is the SI unit of energy?
A. Newton B. Joule C. Pascal D. Ampere
Correct answer: B. Joule
Rationale: Energy and work are measured in joules, where one
joule equals one newton-meter.
, 10. Which mathematical method is commonly used to solve a
system of linear equations?
A. Gaussian elimination B. Differentiation only C. Numerical
integration only D. Fourier transformation only
Correct answer: A. Gaussian elimination
Rationale: Gaussian elimination uses elementary row
operations to reduce a system of linear equations and solve for
its unknowns.
11. What is the moment of a 20 N force acting perpendicular
to a lever arm 3 m long?
A. 6 N·m B. 17 N·m C. 23 N·m D. 60 N·m
Correct answer: D. 60 N·m
Rationale: Moment magnitude is
M=Fd=20(3)=60 N⋅mM=Fd=20(3)=60 N⋅m when the force is
perpendicular to the lever arm.
12. For a body in static equilibrium, which condition must
hold?
A. Net force equals zero only B. Net moment equals zero only C.
Both net force and net moment equal zero D. Acceleration
must increase continuously
Correct answer: C. Both net force and net moment equal zero
Rationale: Static equilibrium requires zero resultant force and
zero resultant moment.
