Challenge Problems

Push your limits with challenges.

Question 1

A bulldozer has an ideal productivity output of 120 loose m³/hr. If the soil density is 1750 kg/m³, determine the adjusted productivity. Apply all relevant correction factors: soil density (0.78), operator skill (0.75), and job efficiency (0.83).

💡 Hint: Start by applying each correction factor sequentially.

Question 2

Analyze a project where the operator is skilled yet job efficiency is low due to poor weather. If the ideal productivity is 150 loose m³/hr with factors of 0.85 for operator skill and 0.6 for job efficiency, calculate the total productive output for a 4-hour operation.

💡 Hint: Consider both skill and job efficiency concurrently.
