Challenge Problems
Push your limits with challenges.
Question 1
A bulldozer's production rate is calculated to be 114.68 loose cubic meters per hour under ideal conditions. If the job efficiency reduces to 50 minutes, and various correction factors apply, what is the new productivity rate?
💡 Hint: Consider both job efficiency and material type adjustment factors.
Question 2
You have a bulldozer that operates efficiently at a soil density of 1365 kg/m³. If it encounters 2000 kg/m³, determine the impact on productivity and the necessary adjustments in productivity calculations.
💡 Hint: Look at the ratio between the ideal density and the actual density.
