Electricity and Control Systems
Engineering Economics and Ethics
Familiarizing yourself with this structure helps you target your study efforts effectively
and use the right sample questions to reinforce your learning.
Types of FE Mechanical Sample Questions
FE mechanical sample questions vary in difficulty and format, but most will test your
ability to apply engineering principles to solve real-world problems. Let’s break down
common categories of questions you can expect.
1. Mathematics and Statistics Questions
Mathematics forms the foundation for many problems in the mechanical FE exam. You
might encounter questions involving calculus, differential equations, linear algebra, and
statistics.
Example sample question:
*Evaluate the integral:*
\[
\int_0^2 (3x^2 + 2x) dx
\]
Solution:
\[
\int_0^2 (3x^2 + 2x) dx = \left[ x^3 + x^2 \right]_0^2 = (8 + 4) - (0 + 0) = 12
\]
Understanding how to quickly evaluate integrals and derivatives can save precious time
during the exam.
2. Statics and Dynamics
These questions assess your understanding of forces, moments, equilibrium, and motion.
Sample question:
*A beam is supported at two points 4 meters apart with a 500 N load placed 1 meter from
the left support. Find the reaction force at the left support.*
Solution:
Let \( R_A \) and \( R_B \) be the reaction forces at the left and right supports, respectively.
Sum of moments about \( R_A \):
\[
R_B \times 4 = 500 \times 1 \Rightarrow R_B = \frac{500}{4} = 125 \text{ N}
\]
Sum of vertical forces:
\[
R_A + R_B = 500 \Rightarrow R_A = 500 - 125 = 375 \text{ N}
\]
This methodical approach of summing forces and moments is crucial to solving statics
problems efficiently.
3. Thermodynamics and Heat Transfer
Thermodynamics questions often involve properties of gases, energy balances, and heat
transfer calculations.
Sample question:
*Calculate the work done during an isothermal expansion of an ideal gas from volume \(
V_1 = 1 m^3 \) to \( V_2 = 3 m^3 \) at 300 K. Assume the gas constant \( R = 8.314 \,
J/mol \cdot K \) and \( n = 2 \, mol \).*
Solution:
Work done in isothermal expansion:
\[
W = nRT \ln \left(\frac{V_2}{V_1}\right) = 2 \times 8.314 \times 300 \times \ln(3) \approx
2 \times 8.314 \times 300 \times 1.0986 \approx 5472 \, J
\]
Memorizing key thermodynamic formulas and understanding when to apply them can
make these questions much more manageable.
4. Fluid Mechanics
Fluid mechanics questions may test concepts like pressure, flow rate, and fluid statics.
Sample question:
*A fluid with density 1000 kg/m³ is flowing through a pipe with a velocity of 3 m/s.
Calculate the dynamic pressure.*
Solution:
Dynamic pressure \( q = \frac{1}{2} \rho v^2 \)
\[
q = \frac{1}{2} \times 1000 \times (3)^2 = 0.5 \times 1000 \times 9 = 4500 \, Pa
\]
These straightforward calculations often come up in the exam, so practicing them is
essential.
5. Mechanical Design and Materials Science
Questions in this category can include stress-strain relationships, failure theories, and
properties of materials.
Sample question:
*A steel rod with a cross-sectional area of 0.01 m² is subjected to a tensile force of 50,000
N. Calculate the stress in the rod.*
Solution:
Stress \( \sigma = \frac{F}{A} = \frac{50,000}{0.01} = 5,000,000 \, Pa = 5 \, MPa \)
Being comfortable with unit conversions and basic formulas is key to answering these
questions correctly.

Examining Sample Questions and Solutions: Practical Examples
To illustrate the value of fe mechanical sample questions and solutions, consider the
following examples:
Sample Question 1: Thermodynamics
A gas undergoes an isothermal expansion at 300 K, increasing its volume from 1 m³ to 3
m³. Calculate the work done by the gas if the initial pressure is 100 kPa.
Solution:
The work done during an isothermal process is given by:
W = nRT ln(V₂/V₁)
Since the pressure and volume are known, and using the ideal gas law, the number of
moles \( n \) can be calculated:
\[
P_1 V_1 = nRT \implies n = \frac{P_1 V_1}{RT}
\]
Given:
\[
P_1 = 100\, kPa = 100,000\, Pa
\]
\[
V_1 = 1\, m^3, \quad V_2 = 3\, m^3
\]
\[
R = 8.314\, J/(mol\,K), \quad T = 300\, K
\]
Calculate \( n \):
\[
n = \frac{100,000 \times 1}{8.314 \times 300} \approx 40.07\, mol
\]
Calculate work:
\[
W = 40.07 \times 8.314 \times 300 \times \ln(3) \approx 40.07 \times 8.314 \times 300
\times 1.0986
\]
\[
W \approx 109,300\, J = 109.3\, kJ
\]
This solution exemplifies a comprehensive approach, integrating formula derivation,
substitution of values, and final interpretation.
Sample Question 2: Mechanics of Materials
A steel rod with a diameter of 20 mm is subjected to an axial tensile load of 10 kN.
Calculate the stress induced in the rod.
Solution:
Stress \( \sigma \) is defined as force divided by the cross-sectional area:
\[
\sigma = \frac{F}{A}
\]
The cross-sectional area \( A \) of the rod is:
\[
A = \pi \times \left(\frac{d}{2}\right)^2 = \pi \times (0.01)^2 = 3.1416 \times 10^{-4}
m^2
\]
Calculate stress:
\[
\sigma = \frac{10,000}{3.1416 \times 10^{-4}} \approx 31.83 \times 10^{6} Pa =
31.83 MPa
\]
This straightforward problem highlights the importance of unit consistency and
fundamental formula application.
