Challenge Problems

Push your limits with challenges.

Question 1

Given a bulldozer model has an ideal production rate of 40 loose cubic meters/hour with correction factors of 0.85 for visibility and 0.75 for material type, calculate the adjusted productivity.

💡 Hint: Multiply the ideal productivity with each correction factor step-by-step.

Question 2

A bulldozer working on a slope with a 10% grade shows a decrease in output to 30 loose cubic meters/hour, while a similar one working on flat ground shows 50. Calculate the correction factor for the slope.

💡 Hint: Think about how terrain directly affects performance.
