Calculate the rolling resistance for a vehicle weighing 30 tons with a rolling resistance value of 25 kg per ton.
💡 Hint: Multiply the weight by the rolling resistance value.
If a tire sinks 5 cm into the surface and the load is 20 tons, calculate penetration resistance using 4 kg per ton per cm.
💡 Hint: Use the formula: (load in tons) * (kg per ton per cm) * (depth in cm).

A tractor weighing 10 tons has a rolling resistance of 40 kg/ton and is hauling a load up a 2% incline. Calculate the total resistance faced.
💡 Hint: Calculate each resistance type separately, then sum.
A truck with a total weight of 30 tons requires 50 kg per ton rolling resistance and operates on a 6% slope. What is the total resistance?
💡 Hint: Use the standard roles of resistance: understand the slope contributes a significant fraction.
