Practice Questions
Test your understanding with targeted questions related to the topic.
Question 1
Easy
What is the swell factor, and why is it important in earth-moving operations?
💡 Hint: Think about how material changes volume during transportation.
Question 2
Easy
Define rolling resistance and give an example.
💡 Hint: Relate it to how heavy vehicles handle different surfaces.

Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is a key reason for the swell factor increase in push-loaded scrapers?
- More weight
- Increased compaction
- Less moisture
💡 Hint: Think about how pushing affects materials physically.
Question 2
Is it true that rolling resistance affects the operation speed of scrapers?
- True
- False
💡 Hint: Consider how resistance works when moving heavy loads.

Challenge Problems
Push your limits with challenges.
Question 1
A construction site requires moving 500 cubic meters of earth involving varied terrains. If the swell factor for the material is 0.8, calculate the required bank cubic meters and the effective load volume using a 10% increase due to push loading.
💡 Hint: Use the swell factor to guide your conversion.
Question 2
Evaluate the cost-effectiveness of using 5 scrapers versus 6 scrapers given a total operating time alongside the associated pusher cycle times to find the optimal operational setup.
💡 Hint: Balance productivity with total costs across both scenarios.
