Challenge Problems
Push your limits with advanced challenges
A bulldozer completes a cycle in 10 minutes under ideal conditions. Calculate the productivity in cubic meters per hour if the blade can carry 1.5 cubic meters and job efficiency is 70%. Then apply a correction factor of 0.8 due to operator inexperience.
💡 Hint: Break down into effective time before applying correction factors.
Calculate the effect of a 15% increase in soil density which drops productivity from 80 to 65 cubic meters. Show how the correction factor helps maintain efficiency.
💡 Hint: Use percentage decrease in productivity to find impacts.
