Challenge Problems

Push your limits with challenges.

Question 1

A bulldozer is located on a site with a 20% incline. If its output is calculated at flat terrain at 10 cubic meters per hour, estimate the corrected output considering the incline.

💡 Hint: Consider how inclines typically affect bulldozer speed and productivity.

Question 2

If the cycle time for a bulldozer is 40 minutes, and the job efficiency is revealed to be only 30 minutes in an hour, calculate the productivity assuming a blade load of 2.5 cubic meters.

💡 Hint: Remember to adjust the calculated productivity based on job efficiency to reflect actual working time.
