EngrD 219 - Fall 2004 Prelim 3 November 17, 2004 Total Points: 100 Time: 8:35 - 9:55 (80 minutes) Name: ______________________________________ (Please initial every sheet) Good Luck!! Please write your solutions in the allocated spaces below the questions. You can use the back of the sheets for scratch work (it will not be graded). The last two sheets of the exam are blank. Write on these two sheets if you need extra room. These two sheets will be graded. If you take apart the pages, staple them when you turn in your exam. Partial credit will be given, but you must show your work to get any credit, and you must box your answer. To receive appropriate credit, be sure to state where you get data that you use in your solutions, e.g. "this number is from table X.X on page Y."
