PAE(01/28/25): (2)Consistency Calculation

What are consistent engineering units?

• A system where different units are used for each calculation

• A system where all quantities adhere to a single unit system

• A system that uses only metric units

• A system that uses only imperial units

Which of the following is a standard unit system mentioned in the text?

• Metric (SI)

• Customary

• Astronomical

• Binary

What units are included in the Metric (SI) system?

• Feet, pounds, seconds

• Meters, kilograms, seconds

• Inches, ounces, minutes

• Yards, stones, hours

What is the primary benefit of using consistent engineering units?

• Increased complexity

• Ensuring compatibility and accuracy

• Reducing the number of units

• Limiting scientific use

Why is unit consistency important in engineering?

• It ensures faster project completion.

• It is the foundation of accurate measurements and computations.

• It reduces the cost of materials.

• It increases the number of workers needed.

What can incorrect unit conversions lead to in real-world applications?

• Increased project funding

• Faster project timelines

• Project failures, such as structural collapses or spacecraft malfunctions

• Improved communication between teams

What was the cause of the Mars Climate Orbiter incident?

• Lack of funding

• Mismatched units between teams

• Poor weather conditions

• Software malfunction

Which units were mismatched in the Mars Climate Orbiter incident?

• Kilograms vs. pounds

• Meters vs. feet

• Newton-seconds vs. pound-seconds

• Liters vs. gallons

Why is it important to use consistent units in engineering projects?

• To increase project costs

• To prevent miscommunication and system failures

• To make projects more complex

• To reduce the need for documentation

What should always be documented in engineering projects?

• Project timelines

• Unit systems

• Employee details

• Budget estimates
