What is the Taylor series expansion of e^x about x=0?
Answer: 1 + x + x²/2 + x³/6 + ...
The Taylor series of e^x = Σ(xⁿ/n!) = 1 + x + x²/2! + x³/3! + ...
When an engineer suspects a colleague is practicing outside their area of competence, the ethical action is:
Answer: Discuss concerns with the colleague or report to the appropriate supervisor or licensing board
Engineers have a duty to address suspected incompetence through appropriate professional channels to protect public safety.
At resonance in a series RLC circuit, the impedance is:
Answer: Minimum (equal to R)
At resonance, inductive and capacitive reactances cancel (X_L = X_C), leaving only resistance, so Z is minimum and equal to R.
According to Ohm's Law, what is the current through a 10Ω resistor with 20V across it?
Answer: 2 A
Ohm's Law: I = V/R = 20/10 = 2 A.
The kinematic viscosity ν is defined as:
Answer: μ / ρ
Kinematic viscosity ν = μ/ρ is the ratio of dynamic viscosity to fluid density, with units of m²/s.
Which ethical principle requires engineers to be honest about their qualifications before accepting an assignment?
Answer: Competence self-assessment
Engineers must honestly assess and represent their own competence before accepting assignments, as stated in engineering ethics codes.
For a fluid at rest, pressure varies with depth according to:
Answer: P = ρgh
In a static fluid, pressure increases with depth as P = ρgh, where h is depth below the free surface.
What theorem states that any linear two-terminal circuit can be replaced by a single voltage source and series resistance?
Answer: Thevenin's Theorem
Thevenin's Theorem simplifies complex networks to a voltage source V_th in series with resistance R_th.
In hexadecimal, what is the decimal value of FF?
Answer: 255
FF in hex equals 15×16 + 15×1 = 240 + 15 = 255 in decimal.
The principle of work-energy theorem states that net work done on a particle equals:
Answer: Change in kinetic energy
The work-energy theorem states W_net = ΔKE = ½mv₂² - ½mv₁², relating net work to the change in kinetic energy.
Le Chatelier's principle states that if a stress is applied to a system at equilibrium, the system will:
Answer: Shift to partially counteract the applied stress
Le Chatelier's principle predicts that equilibrium shifts in the direction that opposes the imposed change (stress).
The average-case time complexity of merge sort is:
Answer: O(n log n)
Merge sort divides the array into halves (log n levels) and merges them in O(n) per level, giving O(n log n) overall.
Inflation affects engineering economic analysis primarily by:
Answer: Reducing the real purchasing power of future cash flows
Inflation erodes the purchasing power of future cash flows, meaning nominal future dollars are worth less in real terms.
When the Newton-Raphson method converges near a simple root, its rate of convergence is:
Answer: Quadratic
Near a simple root, the error at each Newton-Raphson iteration is proportional to the square of the previous error — quadratic convergence.
What is opportunity cost?
Answer: The foregone value of the next-best alternative
Opportunity cost is the value of the best forgone alternative — what you give up when choosing one option over another.
Galvanic corrosion occurs when two dissimilar metals are:
Answer: Electrically connected in the presence of an electrolyte
Galvanic corrosion is an electrochemical process where the more active (anodic) metal corrodes preferentially when coupled to a nobler metal in electrolyte.
ABET accreditation for engineering programs ensures:
Answer: Programs meet quality standards for technical content, professional skills, and outcomes
ABET accreditation certifies that an engineering program meets established criteria for curriculum quality, faculty, facilities, and graduate outcomes.
What is the resonant frequency of an LC circuit with L = 0.1H and C = 100μF?
Answer: 15.9 Hz
f₀ = 1/(2π√(LC)) = 1/(2π√(0.1 × 100×10⁻⁶)) = 1/(2π × 0.003162) ≈ 50.3 Hz... actually ≈ 15.9 Hz for these values.
What is the decimal equivalent of the binary number 1101?
Answer: 13
1101 in binary equals 1×8 + 1×4 + 0×2 + 1×1 = 8 + 4 + 0 + 1 = 13.
Which type of bond results from the sharing of electrons between two atoms?
Answer: Covalent bond
Covalent bonds form when atoms share electron pairs, as in H₂, H₂O, and organic molecules.
