✍️ Sample EIT Questions & Answers

1. On a Mohr's circle, the radius represents:
The maximum in-plane shear stress

The radius of Mohr's circle equals the maximum in-plane shear stress τ_max = (σ₁ − σ₂)/2.

2. Which data structure operates on a Last-In-First-Out (LIFO) principle?
Stack

A stack follows LIFO order—the most recently inserted element is the first to be removed.

3. For a hollow circular shaft in torsion, which parameter most directly increases torsional stiffness?
Increasing polar moment of inertia J

Torsional stiffness = GJ/L; increasing the polar moment of inertia J directly increases stiffness.

4. A perpetuity pays $500 per year forever. If the interest rate is 8%, what is the present value?
$6,250

PV of a perpetuity = A/i = 500/0.08 = $6,250.

5. The specific speed of a pump is used to:
Classify pump type and predict performance at varying scales

Specific speed N_s = N√Q / H^(3/4) classifies pumps (centrifugal, mixed, axial) and guides selection and scaling.

6. According to the NSPE Code of Ethics, engineers shall continue their professional development throughout their careers. Which of the following is an example of fulfilling this obligation?
Attending technical seminars and workshops.

The NSPE Code of Ethics explicitly states that engineers should keep current in their specialty fields by engaging in professional practice, participating in continuing education courses, reading technical literature, and attending professional meetings and seminars. While mentoring, license renewal, and varied work experience are all valuable professional activities, attending seminars and workshops directly addresses the requirement for continuing education and staying current with technical advancements.
