Challenge Problems
Push your limits with advanced challenges
Analyze a scenario where the rolling resistance increases to 60 kg per ton. How does this change the gradient and affect scraper efficiencies?
💡 Hint: Consider how much more energy will be needed now.
If a different material has a swell factor of 1.0 instead of the usual 0.8, how would this affect our weight calculations?
💡 Hint: Think about how the volume change impacts the scraper’s limits.
