1. Production Value of the Bulldozer

Try these first

1. 1.

   Define job efficiency.

   Hint

   Consider the time the bulldozer effectively operates within an hour.

2. 2.

   What is the soil density when the ideal soil is 1365 kg/m³?

   Hint

   Compare it to the ideal standard.

3. 3.

   What is job efficiency?

   • 100% of available time
   • Effective working time as a percentage
   • Time spent on breaks

   Hint

   Think about how to measure productivity.

4. 4.

   True or False: A higher soil density will increase the bulldozer’s productivity.

   • True
   • False

   Hint

   Consider the weight of soil and machinery performance.

5. 5.

   If a bulldozer operates under poor visibility and has a correction factor of 0.8, and the ideal productivity is 100 loose meter cubes per hour, what is the adjusted productivity?

   Hint

   Multiply the ideal value by the correction factor.

6. 6.

   Calculate the total cost per bank meter cube if the bulldozer incurs an operating cost of 1200 rupees per hour and operates at a density-adjusted productivity of 70 loose meter cubes per hour.

   Hint

   Make sure to use the correct conversion for density adjustments in productivity.
