- True
- False
Show hintHide hint
Think about how materials interact when too much is packed.
Question 5.
A construction site has scrapers with a cycle time of 4.5 minutes. If the project shifts to a new area that increases haul time by 30 seconds, what is the new cycle time?
Show hintHide hint
Consider how each increment in time affects the overall cycle.
Question 6.
If a loader scrapes 100 tons in an hour but increases the payload by 100% without modifying the loading efficiency, what will be the effect on the loading time and the production rate?
Show hintHide hint
Analyze the implications of load growth on the overall time.
