Challenge Problems
Push your limits with advanced challenges
A project requires 1000 cubic meters to be moved. If each scraper has a capacity of 19.82 bank cubic meters and takes an average cycle time of 7.78 minutes, how many scrapers would you need to efficiently complete the job in 2 hours?
💡 Hint: Consider the total volume, productivity rates, and how many scrapers would be needed to meet the time limit.
Evaluate how the density of soil (hard vs. loose) affects the production rates. Discuss a strategy to improve production rates if faced with harder soil conditions.
💡 Hint: Think about the relationship between soil condition and equipment performance.
