The exam will cover Lectures 26-37. There will be three full-length questions (no multiple choice or short calculations questions on this exam) on:
- Newton-Euler equations
- Work-energy or impulse-momentum equations
- Vibrations: EOM and natural frequency
Sample exam questions 28-37 are related to the material covered on this exam. Video solutions for these sample exam questions are provided through the links on the left side of the blog. Each video solution is presented on a blog page on which you can directly view and/or add comments. Please use this to provide assistance to and receive assistance from others in the course.
A review video is provided to assist you in your studying for this exam. Click here for a copy of the equation page for Exam No. 3.
A help session is scheduled for 7PM on Monday, December 1 in Room ME 161. This review session will be run a little differently than for the earlier exams. For this help session, you are asked to work through the sample exam questions on your own prior to the help session. Use the solution videos provided to guide you with problems on which you have difficulty. During the help session, I will try to assist you with problems that you are having in general and/or with concepts that might not be clear in the solution videos for the sample exam questions.
Let me know if you have any questions related to Exam No. 3.

I'm having some trouble finding the mass moment of inertia in some problems, would it be possible for you to post a step-by-step method for finding this in general.
Sure, I will give it a try. But first I need to know more about what you are asking.
Three methods of finding the mass moment of inertia:
* Look it up in the back of the book. For the most part, these MMI's are given about the center of mass G or about some special points on the body.
* If the MMI about G is given in the back of the book and you need it about some other point, use the parallel axis theorem: IA = IG + m*d^2, where d is the distance between points G and A. Note that IG must appear on the RIGHT hand side of this PAT equation.
* If the MMI is not given in the back of the book, then you need to use integration. We have examples in the lecture notes (page 50) for finding the MMI about G for a circular disk and a thin bar by integration.
Is your question based on finding the MMI by one of the three methods above? If so, I will try to give you some more background on this. If not, let me know more specifically your question.
Can we see the equation sheet given to us for Exam 3?
I have just attached a link to the equation sheet for Exam No. 3 to this post.
Thanks for the reminder!
Do you have posted anywhere the Quiz solutions?
The quiz solutions were provided at the end of the class period for each quiz for all but Quiz No. 13. Quiz No. 13 is the same as VIB-2, a problem for which a video solution exists on the blog.
