Challenge Problems
Push your limits with advanced challenges
A 50-ton truck encounters a rolling resistance of 25 kg per ton and a 8% grade leading to additional grade resistance. Calculate the total resistance faced by the truck.
💡 Hint: Break down the problem into rolling and grade resistance calculations.
A tractor weighs 12 tons with a rolling resistance of 50 kg per ton. On a flat surface, it operates at an available power of 6000 kg. If it encounters a 3% slope, how much power can it still use for work?
💡 Hint: First compute rolling resistance, then grade resistance, and finally subtract from available power.
