✍️ Sample EIT Questions & Answers
1. Which data structure operates on a Last-In-First-Out (LIFO) principle?
A stack follows LIFO order—the most recently inserted element is the first to be removed.
2. 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?
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.
3. What is the value of the derivative of x^2 at x = 3?
To find the value of the derivative of x^2 at x = 3, first, we apply the power rule for differentiation, which states that the derivative of x^n is nx^(n-1). For x^2, the derivative is 2x^(2-1) = 2x. Next, we substitute x = 3 into the derivative, yielding 2 * 3 = 6.
4. The Henderson-Hasselbalch equation is primarily used to calculate:
pH = pKa + log([A⁻]/[HA]) is the Henderson-Hasselbalch equation for buffer pH.
5. Which material is most likely to follow Hooke's Law?
Hooke's Law describes the linear elastic behavior of materials, stating that stress is directly proportional to strain within the elastic limit. Steel is an excellent example of a material that exhibits a clear and predictable linear elastic region under typical engineering loads, making it suitable for applications where Hooke's Law is applied. Materials like rubber, plastic, and lead often have more complex, non-linear elastic responses or lower elastic limits.
6. Martensite in steel is characterized by:
Martensite forms via a shear (diffusionless) mechanism during rapid quenching, producing a BCT crystal structure that is extremely hard and brittle.
