Challenge Problems
Push your limits with advanced challenges
A bulldozer has a blade capacity of 7 cubic meters and operates with an average cycle time of 25 seconds. How many cubic meters does it produce in an hour assuming perfect job efficiency?
💡 Hint: Make sure to calculate the conversion from seconds to hours.
Given an uphill grade of 20%, if the ideal productivity from production curves is 800 cubic meters per hour, apply a correction factor of 0.8 due to decreased efficiency. What is the adjusted productivity?
💡 Hint: Use the correction factor to refine the estimate.
