Question
Determine the effective grade (%) for the total resistance of goong uphill?

Transcribed Image Text:Facts:
• A fully loaded wheeled scraper (empty weight = 30.0 tons; fully loaded weight = 80.0 tons) must
travel up a 3.0 % slope on a muddy haul road.
The average tire penetration of the machine is estimated to be 4.0 inches.
After dumping the loaded weight, the scraper returns downhill with an empty weight.
Expert Solution

Step 1: step 1
Given data,
Scraper empty weight=30.0 tons
Scraper fully loaded weight=80 tons
slope=3% on muddy haul road
tire penetration= inches
FIND
The effective grade % for the total resistance of going uphill
Step by step
