Question 1.
What is haul distance?
Show hintHide hint
Think about how the distance impacts the efficiency of equipment.
Question 2.
Define rolling resistance.
Show hintHide hint
Consider how different surfaces might affect this concept.
3Question 3.
Why is haul distance important in equipment selection?
- It determines the type of material being excavated
- It affects machine efficiency
- It has no impact on equipment choice
Show hintHide hint
How far the equipment has to travel affects its performance.
4Question 4.
True or False: Rolling resistance can vary based on the surface type.
- True
- False
Show hintHide hint
Recall the examples of hard versus soft surfaces.
Question 5.
Given a construction site with a varied terrain requiring different equipment models to operate, analyze how selecting specific machinery can impact total project costs.
Show hintHide hint
Consider both short-term and long-term costs.
Question 6.
Calculate the required power for a machine with a gross weight of 15 tons moving over a surface with a rolling resistance of 50 kg per ton and determine its effectiveness on an earthen road.
Show hintHide hint
Ensure you account for both rolling resistance and other factors impacting performance.
