The FE Civil exam is a significant hurdle for aspiring civil engineers. Passing requires a deep understanding of core concepts and extensive practice. This post provides a range of FE Civil exam practice questions, categorized for focused study, along with explanations to reinforce learning. Remember, consistent practice is key to success!

Statics and Mechanics of Materials

This section tests your knowledge of fundamental engineering mechanics principles.

1. A simply supported beam with a uniformly distributed load (UDL) experiences maximum bending moment at:

(a) The supports (b) The mid-span (c) One-third of the span from either support (d) One-quarter of the span from either support

Answer: (b) The mid-span. The maximum bending moment in a simply supported beam with a UDL occurs at the center of the beam.

2. What is the relationship between stress (σ), strain (ε), and Young's modulus (E) for an elastic material under uniaxial stress?

(a) σ = ε/E (b) σ = E/ε (c) σ = Eε (d) σ = ε - E

Answer: (c) σ = Eε. This is Hooke's Law, defining the linear elastic behavior of materials.

3. A steel rod with a cross-sectional area of 2 cm² is subjected to a tensile force of 10 kN. If the Young's modulus of steel is 200 GPa, what is the resulting stress?

(a) 5 MPa (b) 50 MPa (c) 500 MPa (d) 5000 MPa

Answer: (b) 50 MPa. Stress (σ) = Force (F) / Area (A) = 10,000 N / (2 x 10⁻⁴ m²) = 50 x 10⁶ Pa = 50 MPa

Fluid Mechanics

This section examines your understanding of fluid behavior and principles.

1. What is the pressure at a depth h below the surface of a fluid with density ρ and gravitational acceleration g?

(a) ρgh (b) ρg/h (c) ρh/g (d) g/ρh

Answer: (a) ρgh. This is the hydrostatic pressure equation.

2. What principle describes the relationship between the pressure and velocity in a flowing fluid?

(a) Archimedes' Principle (b) Bernoulli's Principle (c) Pascal's Principle (d) Newton's Second Law

Answer: (b) Bernoulli's Principle. This principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in static pressure or a decrease in the fluid's potential energy.

3. A pipe carrying water has a diameter of 10 cm at section A and 5 cm at section B. If the velocity at section A is 2 m/s, what is the velocity at section B (assuming incompressible flow)?

(a) 1 m/s (b) 2 m/s (c) 4 m/s (d) 8 m/s

Answer: (d) 8 m/s. Using the principle of continuity (A₁V₁ = A₂V₂), the velocity at section B is four times that of section A.

Transportation Engineering

This section focuses on the planning, design, and operation of transportation systems.

1. What is the primary function of a superelevation on a highway curve?

(a) To increase friction (b) To reduce braking distance (c) To counteract centrifugal force (d) To improve drainage

Answer: (c) To counteract centrifugal force. Superelevation tilts the roadway to help vehicles navigate curves safely at higher speeds.

2. What does the acronym HOV stand for in transportation engineering?

(a) High Occupancy Vehicle (b) High-speed On-ramp Vehicle (c) Heavy-duty Off-road Vehicle (d) Highway Overpass Vehicle

Answer: (a) High Occupancy Vehicle. HOV lanes are designed to encourage carpooling.

3. What is the primary factor considered when designing the length of a passing sight distance on a two-lane highway?

(a) Vehicle speed (b) Road curvature (c) Road gradient (d) All of the above

Answer: (d) All of the above. All factors are crucial in ensuring safe passing maneuvers.

This is just a small sample of the types of questions you might encounter on the FE Civil exam. Remember to review all relevant topics thoroughly and practice extensively using official FE Civil exam preparation materials and practice exams. Good luck!
