Question 1
What is the formula for calculating rolling resistance?
- Weight in tons * Rolling resistance per ton
- Weight in kg / 1,000
- Weight of tire pressure
💡 Hint: Think about how weight changes in terms of tonnage.
Question 2
True or False: Grade resistance increases as the slope of a hill increases.
- True
- False
💡 Hint: Consider how gravity affects your movement uphill.

Challenge Problems
Push your limits with challenges.
Question 1
A tractor with a gross weight of 20 tons faces a rolling resistance of 50 kg/ton and climbs a 3% slope. Calculate the total tractive effort required.
💡 Hint: Remember to calculate each resistance component and sum them.
Question 2
If a vehicle weighs 10 tons and sinks 7 cm into the surface with a rolling resistance of 70 kg/ton, is the total resistance more than 1300 kg?
💡 Hint: Breaking down into smaller components will help clarify the total!
