What aspects of the course did you think were most effective at helping you learn? (Answer in thoughtful, complete sentences)

The BAT Cave on D2L helped me prepare for exams and quizzes

Continue with question #15,Please calculate the hourly fuel cost if the wheel loader has a 250-fwhp diesel engine, and the diesel fuel costs $1.20 per gallon, and the operating factor (combined factor) is 0.75. (See textbook page 47 Example 2.12 for reference)

Continue with question #15,Please calculate how many sets of tires are needed during the 10 years’ of operation of this loader assuming one set of tires can be expected to last 4,000 hours, and the loader will be operated 2,000 hours per year.

Continue with question #15,How much is the hourly oil and grease cost if the equipment operating factor (combined factor) is 0.5, the crankcase capacity is 15 gallons, the flywheel horsepower rating of the loader’s diesel engine is 105 fwhp, the time between oil changes is 250 hours, the cost of lube oil is $3.0/gal, and the cost of other oils and grease is $0.5/hr. (See textbook page 47 Example 2.13 for reference)

Thanks to this course, I can explain what the critical zone is and how it supports life on Earth

TIres for wheel-type equipment are a major operating cost, because they have a short life in relation to the iron of a machine.

O&O costs are usually expressed in dollars per equipment operating hour.

Match the adaptive cycle phase name with an example of that phase

Rocks that cool from magma slower, deeper within the earth develop _______ (smaller/larger) crystals than ones that grow faster and closer to the surface. As average crystal size in a rock increases, weathering rate _______ (increases/decreases). As the iron content of a rock increases, weathering rate _______ (increases/decreases).
