HEADS-UP: Also, regarding the grading of homework, please pay attention to the instructions given on the syllabus. (Write neatly and orderly, use engineering paper, box in your answers, staple the homework in the upper left). If you don't follow any of these directions, your graders will penalize you quite severely, so please be careful. It is particularly important to be very neat and to show all of your work.

(1/9): Welcome to your engineering dynamics course link. Please bookmark this page, and make hard copies of the syllabus and course description linked above. Notices will be posted here, so it will be good to check this page out from time to time. The derivations that you will be responsible for are listed here.

Note that your first hw assignment is due this Thursday, January 17.

ENGINEERING DYNAMICS SUMMER I 2002

Note to Students (5/22): The summer I session is a good time to take engineering dynamics. The class will move very fast, and be over in about 4 weeks (the first day of classes is Mar 22 and the last day is June 25) and you'll have time to concentrate on one class rather than have to balance your time with many classes. It is not recommended that you take another serious class during this summer I session while you're taking engineering dynamics because of the work load and the studying that is required in this class.

Please make copies of the syllabus and course description and follow them carefully. Large homework sets are due about every other day, so it's easy to fall behind. I wish you all the best of luck!
