Challenge Problems
Push your limits with advanced challenges
A scraper has a fixed loading time of 0.8 min, increased resistance when over 85% loading leads to an effective new loading time of 1.5 min after that point. Calculate the difference in cycle time if loading 90% payload is attempted.
💡 Hint: Consider the totality of the cycle time when calculating efficiencies.
Given varying haul route conditions affecting machine speed, calculate the haul time if the distance is 200 meters and average speed is 10 m/s. Adjust for resistance factors diminishes speed to 7 m/s.
💡 Hint: How do different speeds impact the time taken to cover the same distance?
