Question 1 1 pts Motor Graders work just as well performing mass excavation as does dozers, scrapers, and excavators. 0 True 0 False Question 2 1 pts Graders work very well for maintaining the earth haul roads used by scrapers and trucks on johsites. 0 True 0 False Question 3 1 pts When using a grader to grade a large area such as a parking lot or large commercialfindustrial building pad, which of the following methods typically make the most sense? 0 Unear Grading Method 0 Back and Forth Method 0 Looping Method 0 Roadway Method D Question 4 1 pts When using the looping method with a grader to grade a large area such as a parking lot or large commercial/industrial building pad, which of the following is true? O Typically, going back and forth on the shortest side is best (travel distance is shortest). O Typically, going back and forth on the longest side is best (travel distance is longest). It really doesn't matter as the linear grading method is far superior. O It doesn't matter as it will always result in the same answer. D Question 5 1 pts Sometimes it makes sense to calculate the productivity for graders in square yards per hour rather than cubic yards per hour. When might you do this? O When grading a parking lot. O When grading a building pad. O When trying to balance the number of graders with the material being hauled in from the excavation site. O When grading a haul road. D Question 6 1 pts Which of the following is the correct formula for the back and forth method when calculating the cycle time of graders? O Or _ distance grading distance backing (aug mph) mia (aug mph) min O CT = distance grading (w)(turning radius (avg mph) (aug mph) Thigh O p_ (aug speed ] (effective width)(operating factor) twinber of passes required O p _ (distance)(eff. width) (O.B.)(depth) (CT) (number of passes) (9- )
