Challenge Problems
Push your limits with challenges.
Question 1
For a scraper with a gross weight of 80,000 kg and a coefficient of traction of 0.6, calculate the effective rimpull available after accounting for 2% rolling resistance and a 5% deduction at 900 meters.
💡 Hint: Carry out each step incrementally, considering the deductions along the way.
Question 2
A scraper operates at an altitude affecting its engine efficiency and traction. Given the same parameters as the above, how would the results differ if it operated at a coastal level versus 1,200 meters altitude?
💡 Hint: Compare the rimpull outcomes at different altitudes, paying attention to percentage deductions.
