4Question 4.
True or False: The height of cut directly influences the correction factor.
- True
- False
Show hintHide hint
Consider why we use correction factors.
Question 5.
A project has an excavator that can operate at a maximum height of 8 m. If optimizing for soft soil you choose 30% of that height, what is your optimum height?
Show hintHide hint
Use the percentage of maximum height to determine optimums.
Question 6.
