Homework 6- Chapter 9 Problem 1: A crawler hoe having a 2 -cy bucket and whose cost per hour, including the wages to an operator, is $109 will excavate and load haul units under each of the stated conditions. The maximum digging depth of the machine is 22 ft. Determine the cost per bank cubic yard for each condition. (Condition 1: 315 bey/hr, S0.346/bcy; condition 2: 289 bey/hr, S0.377/bcy;...

please help me.
Problem 2: Evaluate cost and production using a 3-cy hoe to load wet gravel (2980 lb/lcy) into 14 cy trucks. Assume a bucket fill factor of 105% and that the hoe bucket swing cycle time is 24 sec. the truck empty weight is 36860 lb, and a rated payload of 40000 lb. Dump time will be 1.3 min. the haul distance is 2.5 miles from the pit to the plant up a 3% grade. The rolling resistance...

(50) 7. Analyze the following operation. A 385C Excavator will be used to load material into a CAT 740 (no ejector) articulated truck. The excavator is equipped with a 6 cy heaped bucket and is capable of cycling every 30 seconds. The material being loaded weighs 3,300 lbs cy. The job efficiency is 90%. The trucks will be hauling the nmaterial 4000 feet over a road with a total rolling resistance of 9% to the dumpsite and 10% total rolling...
