The 988H is now working the gravel stockpile and the conditi

The 988H is now working the gravel stockpile and the conditions are level (no grade) but the ground conditions are now loose gravel. The pitrun weighs 3250 pounds per cubic yard and the bucket size is still 10 cy. What is the rolling resistance of the 988H in pounds per ton? Express the answer in pounds.

Solution

Solution:-

Given

Bucket size = 10 cubic yard

Weight of pitrun = 3250 *10 = 32500 pounds

Weight of pitrun = 16.25 ton

Let weight of 988H = 50 ton

Total weight of full loaded 988H = 50 + 16.25 = 66.25 ton

Rolling resistance factor = 40 lb/ton

Rolling resistance = Rolling resistance factor * Total weight of 988H

Rolling resistance = 40 * 66.25

Rolling resistance = 2650 pound     Answer
