Which of the following is not a part of the oil pump?
oil galleries

Alex loaned Charlie $300 at an annual interest rate of 6%. If no payments are made, what is the interest owed on this loan at the end of the first year?
The yearly interest charged on this loan is the annual interest rate multiplied by the amount borrowed:

Opposed cylinder designs feature two rows of cylinders that are placed at what angle to each other?
