Challenge Problems
Push your limits with advanced challenges
A construction equipment weighing 70,000 kg operates on a poorly maintained earthen road. The rolling resistance is 90 kg per ton. Calculate the total rolling resistance and discuss the strategies to minimize this.
💡 Hint: Think about both calculation and operational strategies.
A track-loader handling 40 tons has a low rolling resistance of 25 kg per ton when operating on a well-maintained surface. What would be the total tractive effort required, and how could this change on a soft, uneven surface?
💡 Hint: Consider the factors affecting resistance on varying surfaces.
