Challenge Problems
Push your limits with challenges.
Question 1
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.
Question 2
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.
