Use a CAT $730$C$2$ EJ Articulated Haul Truck $($Tier $4$ final$/$Stage IV$/$Japan $2014)$ for this problem. The truck is hauling broken granite on a $3\%$ grade and the haul road rolling resistance is $60$ lb$/$tn$.$ No correction is required for altitude. Use ISO net power. In case you$$re not familiar with articulated haul trucks; they have six $(6)$ wheels and their all$-$wheel drive.

Find:

A$.$ Calculate the maximum weight of material the truck can handle for haul. Which

controls: volume or weight of material? Also calculate volume of load in LCY$.$

B$.$ Calculate the Required Power in lbs for haul and return trip $($use equation

method$).$

C$.$ Calculate Available Power in terms of Rimpull $($lbs$),$ speed and gear for haul and return trip $($use hand calculations and CAT Rimpull$-$Speed$-$Gradeability chart$).$ Turn in chart with marked lines to show how you calculated Rimpull, speed and gear.

D$.$ Are the haul and return speeds reasonable and why? If not, what is a reasonable

speed?

E$.$ The haul road has good traction wet or dry. However, during the winter months the haul road is covered in packed snow and$/$or ice. Does the truck have enough traction hauling loaded and returning empty for snow and ice conditions only? Calculate all

four $(4)$ scenarios and state yes or no for each; $1)$ Haul snow, $2)$ Return Snow, $3)$ Haul ice, $4)$ Return ice. If the front wheel drive was out of service, would the truck have enough traction to make the haul only in snow and ice? Two more scenarios for a total of $6$ calculations; $5)$ Haul snow w$/$ front drive out, $6)$ Haul ice w$/$ front drive out.
