Challenge Problems
Push your limits with advanced challenges
A vehicle weighs 20 tons and has a rolling resistance of 30 kg per ton. If it travels on a 6% slope, calculate the total tractive effort required.
💡 Hint: Use the formulas for both rolling and grade resistance, then sum them up.
If a machine with a maximum rimpull of 9000 kg faces 2000 kg of rolling resistance and 1500 kg of grade resistance, how much effective pull does it have left?
💡 Hint: Calculate total resistance then subtract it from maximum rimpull.
