Challenge Problems

Push your limits with challenges.

Question 1

A bulldozer weighs 50,000 kg with a rolling resistance of 35 kg per ton and sinks 10 cm into the ground. Calculate the total tractive effort needed to move it.

💡 Hint: Calculate rolling resistance first, then add the penetration component.

Question 2

Consider a project where a truck with a gross weight of 40 tons moves on a slope. If the grade resistance is rated at 15 kg per ton, how does this affect the tractive effort calculation?

💡 Hint: Ensure to consider both components of resistance to get the full picture.
