2 cards from this section. Quick, good the night before a test.
What is the ideal soil density referenced for productivity calculations?
Think about the standard condition mentioned.
Define what a correction factor is.
Consider how it relates to ideal vs. actual performance.
What is the ideal soil density for productivity adjustments?
Refer to the given values in the section.
True or False: An operator with average skills will increase the productivity of a bulldozer.
Think about how skill affects work speed.
A bulldozer's production curve indicates 120 loose m³/hour based on ideal conditions. Due to clay soil with density at 1800 kg/m³, the operator is of average skill, and visibility is low. Calculate the adjusted productivity.
Multiply the original curve value by the product of the correction factors.
If operating costs rise by 20% in your project due to unforeseen expenses, recalculate the unit cost if original operating cost was 2000 rupees and original productivity was maintained at an estimated 60 bank m³/hour.
First adjust costs, then divide by productivity.
