Question 1

What is the formula to calculate total rolling resistance?

  • Vehicle Weight in kg x Rolling Resistance
  • Vehicle Weight in tons x Rolling Resistance per ton
  • Rolling Resistance + Penetration Resistance

💡 Hint: Remember the units used in the calculation.

Question 2

True or False: Penetration resistance is calculated based on the depth of tire penetration and vehicle weight.

  • True
  • False

💡 Hint: Think about what determines penetration resistance.

Question 1

Calculate the total resistance for a vehicle weighing 25 tons with a rolling resistance of 35 kg per ton and a tire penetration of 10 cm into a soft ground.

💡 Hint: Separate your calculations for rolling and penetration resistances.

Question 2

If rolling resistance changes to 45 kg/ton for a vehicle that weighs 60 tons and the depth of penetration increases to 8 cm, what is the new total resistance?

💡 Hint: Use the same formulas and remember to recalculate each resistance.
