3 cards from this section. Quick, good the night before a test.
What is the correction factor for job efficiency if a bulldozer operates 50 minutes in an hour?
Calculate using (50/60).
Define soil density and its impact on productivity.
Think about what happens when soil is denser.
What does the job efficiency correction factor represent?
Think about how working less than an hour affects productivity.
True or False: Higher soil density always increases bulldozer productivity.
Consider what happens when the material is heavier.
You have a bulldozer with a theoretical productivity of 120 m³/hr. The job is in a dense clay area at 1800 kg/m³, an average operator, poor visibility, and job efficiency of 45 minutes per hour. Calculate the adjusted productivity.
List all necessary correction factors you'll need to apply and calculate step by step.
A bulldozer operates at a cost of 1500 rupees per hour and achieves a production rate of 70 bank meter cubes per hour. Determine the cost per meter cube and analyze what factors might influence this calculation positively or negatively.
Make sure to apply the proper formula to find out the cost and identify any variable factors.
