1. You will be using a Motor Grader to clean off a section of highway that it 36-feet wide plus two 8-foot shoulders for a total width of 52-feet. You will assume that there is sufficient space outside the shoulders for material to be stockpiled as part of your cleaning efforts. You are to assume an overlap of 2-feet and an operating speed of mph. The length of roadway to be cleared is 14,600 long. You have available to you the following equipment: a. MG 135H ($165/hr with a 12-foot moldboard that operates at a blade angle of 30 degrees) - $15,000 delivery/mobilization/takeaway - job efficiency of 85% b. MG 140H ($225/hr with a 12-foot moldboard that operates at a zero degree blade angle) - $20,000 delivery/mobilization/takeaway- job efficiency of 80% c. MG 16M ($300/hr with a 16-foot moldboard that operates at 30 degrees) - $25,000 delivery/mobilization takeaway - job efficiency of 90% d. MG 24M ($400/hr with a 24-foot moldboard that operates at 45 degrees) - $30,000 delivery/mobilization/takeaway - job efficiency of 88% Determine the following: Which option is the most cost effective? 2. For the other three options that were the "less cost effective" from Problem #1 what would each less cost effective" option's moldboard length need to be revised to - at a 30 degree degree moldboard angle for their costs to be the same as the best cost option determined in
