Question 1.
If a vehicle weighs 30 tons with a rolling resistance of 25 kg per ton, what is the total rolling resistance?
Show hintHide hint
Multiply the weight in tons by the rolling resistance per ton.
Question 2.
How is vehicle weight converted from kilograms to tons?
Show hintHide hint
Remember the conversion factor.
3Question 3.
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
Show hintHide hint
Remember the units used in the calculation.
4Question 4.
True or False: Penetration resistance is calculated based on the depth of tire penetration and vehicle weight.
- True
- False
Show hintHide hint
Think about what determines penetration resistance.
Question 5.
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.
Show hintHide hint
Separate your calculations for rolling and penetration resistances.
Question 6.
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?
Show hintHide hint
Use the same formulas and remember to recalculate each resistance.
