Challenge Problems

Push your limits with challenges.

Question 1

A construction project sits at an elevation of 8,000 feet. How would you calculate the necessary adjustments to machinery performance in terms of usable power?

💡 Hint: Consider how atmospheric changes relate to power capabilities.

Question 2

You have a performance chart that shows an engine can produce 200 horsepower at sea level. At an altitude of 6,000 feet, the same engine is projected to produce only 150 horsepower. How would this influence your choice of machinery for a heavy-hauling project?

💡 Hint: Factor in potential increases in rolling resistance at altitude.
