Short Application Assessment

Please complete the following six questions as part of your application. This exercise should take no more than 10 to 15 minutes.

You may use ChatGPT or other online resources. AI tools are part of this position. However, you are responsible for determining whether information provided by AI is correct.

Where quiz questions are shown, the answer that is intended to be the “correct” answer is shown in bold font.

While taking this assessment, keep these things in mind:

• Check engineering terminology for accuracy and consistency.
• Review engineering units, numerical values, calculations, equations, tables, charts, figures, and captions.
• Identify inconsistencies within course material.
• Review spelling, grammar, punctuation, and clarity.
• Review references to engineering standards, codes, and regulations and identify potentially outdated information.
• Verify that quiz questions can be answered using the course material and that designated quiz answers are correct.
• Identify ambiguous questions or situations in which more than one answer could reasonably be considered correct.
• Identify poorly written quiz questions that have obviously incorrect wrong answer choices.
• Verify issues that require additional review rather than making unsupported technical corrections.

 

For each recommendation, select:

1. ACCEPT — No changes are required.
2. REJECT and MODIFY — The course, quiz questions, and/or answer(s) need to be changed.
3. VERIFY — You would not make any changes without additional research.
4. Briefly explain your reasoning.

Question 1

Course statement:

"The 15-kW motor operated continuously for 4 hours and consumed approximately 60 kWh of electrical energy."

ChatGPT recommendation:

Change "60 kWh" to "60 kW." Since the motor is rated in kilowatts, its electrical consumption should also be expressed in kilowatts.

Question 2

ChatGPT reviews a course and suggests the following quiz question. Assume that the knowledge needed to answer the question is contained in the course and ChatGPT has correctly identified the right answer B, which is in bold font.

"What is a key benefit of high psychological safety in engineering teams?"

A. More hidden mistakes

B. Increased hazard reporting and innovation

C. Reduced team communication

D. Slower decision making

Based on your quick inspection of the question and answers, do you see any problems that would necessitate making change(s) to the question or answer(s)?

Question 3

Course statement:

"Common methods of heat transfer include conduction, convection, and radiation."

Quiz Question:

"Which of the following is a common method of heat transfer?"

A. Conduction

B. Convection

C. Radiation

D. Combustion

Do you see any problems that would necessitate making change(s) to the course statement, the quiz question or the quiz answer(s)?

Question 4

Course statement:

"Doubling the diameter of a circular pipe will double its cross-sectional area"

Quiz Question:

"A piping engineer increases the feedwater pipe to a boiler from 1” NPS to 2” NPS. The cross-sectional area of the new 2” diameter pipe will be approximately ________ as much as the original 1” diameter pipe."

A. 1.5 times

B. 2 times

C. 4 times

D. 8 times

Do you see any problems that would necessitate making change(s) to the course statement, the quiz question or the quiz answer(s)?

Question 5

Course text:

"Gases and Vapors"

Many common industrial hydrocarbon gases and solvents are flammable in air over the range 1 - 12% by volume. This is referred to as the flammable or explosive range existing between the lower explosive limit (LEL) and the upper explosive limit (UEL). The electrostatic discharge energy required for ignition varies significantly over this range but the minimum ignition energy value is likely to be of the order of 0.2 - 2.0 millijoules (mJ). This energy level is very low and indicates that ignition may result easily.

The relationship between the minimum ignition energy of the solvent vapors and their concentration will be similar to that shown by the red U-shaped curve in Figure 3. Note that the solvent is most sensitive to ignition near the lower and upper flammable limits and that the spark energy required to ignite the vapor increases rapidly as it approaches these limits."

Figure 2. Typical relationship between ignition sensitivity and concentration of fuel vapor in air

Quiz Question:

The electrostatic discharge energy required for ignition of hydrocarbon solvent vapors is lowest (indicating that ignition may result easily) __________.

A. Midway between the lower and upper flammable limits

B. Near the lower flammable limit

C. Near the upper flammable limit

D. Both (B) and (C)

Question 6

Quiz question:

A rectangular tank holding water measures 50 ft wide x 20 ft long x 10 ft high. The tank is 75% full. An operator then drains 500 gallons from the tank. What volume of water is left remaining in the tank?

A. 451 ft²

B. 537 ft²

C. 683 ft²

D. 852 ft²
