4 cards from this section. Quick, good the night before a test.
What is a correction factor?
Think about adjustments needed due to different soil conditions.
Why is job efficiency important?
Consider how long a machine can practically work in an hour.
What is the first step in calculating bulldozer productivity?
Consider what needs to be established before adjustments.
True or False: Soil that is denser than the productivity curve will increase productivity.
Think about how difficult soil conditions affect machinery operations.
A bulldozer has an ideal productivity of 120 loose cubic meters per hour on level terrain. If job efficiency is only 45 minutes, and soil density is modified at 1800 kg/m³ with average operator skill. Calculate the final productivity considering the necessary correction factors.
Use the factors step by step to ensure accuracy in the productivity calculation.
Explain how to derive the adjustment for unit cost if the total costs per hour increase by 10% due to higher wages and equipment wear, while output remains unchanged. Calculate and give the new unit cost if the previous unit cost was 30 rupees.
Think about how costs and outputs are correlated in these calculations.
