Challenge Problems
Push your limits with challenges.
Question 1
A vehicle has a total weight of 80 tons with a rolling resistance of 35 kg per ton and is facing a grade resistance of 6% slope. What is the total resistance using these values?
💡 Hint: Calculate each resistance type, and add them together.
Question 2
If a load weighs 25 tons with a rolling resistance of 25 kg per ton and is on a flat road, but needs to transition to a 3% slope. How much additional tractive effort is necessary?
💡 Hint: Remember to calculate rolling and grade resistances separately.
