Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

What is the primary advantage of having more scrapers than needed?

💡 Hint: Think about who controls the process in terms of the number of machines.

Question 2

Easy

In unit cost analysis, what two costs are typically included?

💡 Hint: Consider what machinery operates on a job.

Interactive Quizzes

Engage in quick quizzes to reinforce what you've learned and check your comprehension.

Question 1

What does it mean when the number of scrapers is less than ideal?

  • Production is controlled by pushers
  • Production is controlled by scrapers
  • Production is unaffected

💡 Hint: Think about which machine waits on the other.

Question 2

True or False: If there are more scrapers than needed, the pusher's cycle time does not matter.

  • True
  • False

💡 Hint: Consider what influence the pusher has in that scenario.

Challenge Problems

Push your limits with challenges.

Question 1

Given a scenario with 4 scrapers, each with a cycle time of 9 minutes, calculate the production in bank cubic meters per hour and discuss how this impacts project timelines.

💡 Hint: Utilize the formulas provided in our discussions.

Question 2

Analyze both scenarios presented in the conclusion—5 vs. 6 scrapers—and determine whether productivity or cost should take precedence based on the project description.

💡 Hint: Consider project deadlines and budget constraints.
