Challenge Problems

Push your limits with challenges.

Question 1

A construction company needs to perform excavation work at an elevation of 8,000 feet. Calculate the expected decrease in horsepower if the rated output at sea level is 100 horsepower. Justify your calculation.

💡 Hint: Think about standard adjustment percentages used in engineering practices.

Question 2

If a turbocharger efficiently increases the air intake but runs at a temperature exceeding the optimal level, discuss how this will impact performance. What can be done to mitigate these effects?

💡 Hint: Consider how cooling systems affect performance in high-stress environments.
