5 cards from this section. Quick, good the night before a test.
What is the correction factor for a machine that operates for 50 minutes per hour?
Calculate the time operated divided by total ideal time.
How does soil density affect productivity?
Consider the extra effort required to move denser soil.
What is the correction factor for a machine operating under lower job efficiency?
Think about how operating less time affects the numbers.
True or False: Higher soil density improves productivity.
Reflect on what makes soil easier or harder to move.
A machine operates for 50 minutes in an hour, moving soil that has a density of 1750 kg/m³. If the ideal curve provides a productivity of 100 cubic meters per hour for 1365 kg/m³ density, find the final adjusted productivity.
Break the calculations into smaller parts: job efficiency and density adjustments.
Discuss how an operating bulldozer on a -10% slope, in foggy conditions with an average operator, would affect productivity. Provide the expected correction factors.
Consider how each condition modifies the expected productivity metric.
