Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

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.

Question 2

Easy

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).

Question 1

What is the rolling resistance for a vehicle weighing 50 tons with a rolling resistance of 30 kg per ton?

  • 1500 kg
  • 1200 kg
  • 4000 kg

💡 Hint: Think of the formula: Weight (in tons) multiplied by Resisting Force (in kg/ton).

Question 2

True or False: Grade resistance only applies when going downhill.

  • True
  • False

💡 Hint: Consider the direction of the slope.

Challenge Problems

Push your limits with challenges.

Question 1

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.

Question 2

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.
