Challenge Problems
Push your limits with challenges.
Question 1
A backhoe weighs 25 tons, and the rolling resistance is 80 kg per ton. If it's working on a soft soil surface that causes a penetration of 5 cm, calculate the total tractive effort needed.
💡 Hint: Add the rolling force to the force from penetration.
Question 2
Consider a bulldozer with a gross weight of 60,000 kg, having a rolling resistance of 30 kg/ton. If it sinks by 10 cm in unstable terrain, how much force will be needed to keep it moving?
💡 Hint: Use rolling resistance and penetration resistance calculations as separate parts.
