Challenge Problems

Push your limits with challenges.

Question 1

A bulldozer has a blade load capacity of 2.0 loose cubic meters and a cycle time of 2.5 minutes. How many loose cubic meters can it push in an hour if the job efficiency is 50%?

💡 Hint: Keep in mind job efficiency affects overall output.

Question 2

If the bulldozer works in a site with a higher material density that modifies productivity by 30% lower from a base of 100 loose cubic meters per hour, what is the adjusted productivity?

💡 Hint: Think about how density affects bulldozer performance!
