2 cards from this section. Quick, good the night before a test.
What are the basic steps of an earthmoving operation?
Think about the sequence of tasks involved.
What is rolling resistance?
Consider what physical factors might create resistance in movement.
What is the primary purpose of earthmoving in construction?
Think of the broader activities involved in earth construction work.
True or False: The only factor influencing equipment selection is the haul distance.
Consider the various aspects of machinery use in different conditions.
You need to move a total of 80 tons of soil with a rolling resistance of 45 kg per ton and a sink of 4 centimeters. What is the total tractive effort required?
Calculate each part step by step.
In an excavation project, the haul distance for bulldozers is 100 meters, and for scrapers, it’s 1000 meters. If a project requires 500 tons of material to be moved with bulldozers, how many runs will be required assuming each can move 5 tons at a time?
Break down the total weight based on equipment capacity.
