Question 1

What is the correction factor for a machine operating under lower job efficiency?

  • Greater than 1
  • Less than 1
  • Equal to 1

💡 Hint: Think about how operating less time affects the numbers.

Question 2

True or False: Higher soil density improves productivity.

  • True
  • False

💡 Hint: Reflect on what makes soil easier or harder to move.

Challenge Problems

Push your limits with challenges.

Question 1

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.

💡 Hint: Break the calculations into smaller parts: job efficiency and density adjustments.

Question 2

Discuss how an operating bulldozer on a -10% slope, in foggy conditions with an average operator, would affect productivity. Provide the expected correction factors.

💡 Hint: Consider how each condition modifies the expected productivity metric.
