Question 5.
A bulldozer is expected to operate on soil with a density of 1600 kg/m³, while the ideal curve is for 1365 kg/m³. Calculate the necessary correction factor and its impact on a productivity estimate of 80 loose cubic meters.
Show hintHide hint
Always convert densities to see how they affect productivity.
Question 6.
If the budget for operating a machine is Rs. 1500 per hour and the estimated productivity is 60 bank meter cubes, what would be the new cost per bank meter cube if the hourly cost rises to Rs. 1800?
Show hintHide hint
Reassess your budget and divide by the productivity to find costs.
