Define rolling resistance.
Show hintHide hint
Think about the type of surfaces involved.
Question 2.
What unit measures rolling resistance?
Show hintHide hint
Refer to the context of measurement in the lecture.
3Question 3.
What primarily defines rolling resistance?
- The opposition to motion on a surface
- The support capacity of the surface
- The friction experienced by tires
Show hintHide hint
Think about what surfaces interact with wheels.
4Question 4.

- True
- False
Show hintHide hint
Consider how tires perform in different environments.
Question 5.
Calculate the total tractive effort for a vehicle weighing 25 tons if the rolling resistance is 45 kg per ton and if the tire penetration is 5 cm.
Show hintHide hint
Break it down into two parts: normal rolling resistance and penetration components.
Question 6.
Discuss the economic implications of maintaining roads for rolling resistance—how does it affect project budgets?
Show hintHide hint
Think about the long-term operational costs and savings.
