Welcome to Physics 326: Intermediate Mechanics II The instruction for this course will begin at 11:00 am on Tuesday, Aug 27, 2013 in 144 Loomis Laboratory of Physics (LLP). The schedule (subject to change) can be found here.
Physics 326 is the second half of the complete classical mechanics sequence (Physics 325 is the first half). The structure of the course is very like that of last semester's. It is planned that the course will include material on multi-degree of freedom coupled linear oscillations, rotations of 3-d rigid bodies, a bit of chaos and nonlinear dynamics, and some continuum mechanics including waves in solids and fluids. See the schedule for details.
* Taylor, Classical Mechanics
* Marion and Thornton, Classical Dynamics of Particles and Systems. The Fifth
Edition is best, but earlier editions are also fine.
I've put these books on reserve for PHY 326 in Grainger Library.
* new feature: A booklet of 183 pages constituting an edited version of the lecture notes from last year is available at the Illini Union Bookstore (if they run out let them/me know). Many students asked for this; purchasing it is not required. Reading it before class will give you an opportunity to familiarize yourself with the material of the lecture before the lecture is presented. It is planned that the schedule page will indicate which pages of those "Approximate Lecture Notes" are relevant to each day's lecture.
Some of the on-line activities (e.g. gradebook) for this course run on a secure server and must be logged into. Students enrolled in (and staff associated with) the course must log in using their UIUC NetID and their NetID password. If you are enrolled in the course and are having trouble logging in, send email to Rebecca Wiltfong firstname.lastname@example.org. You should always log out of the secure server at the end of your session.
Lectures will be held on Tuesdays and Thursdays from 11:00-12:20 in 144 Loomis. Most lectures will have a 5 minute break in the middle, and a 5 minute mini-quiz at the end. Official lecture notes will be posted after each class at the course website. These notes may differ from those available for hard-copy purchase at the beginning of the semester.
The problem sessions will take place weekly (starting Aug 30). There are four problem sessions scheduled, each lasting one hour every Thursday starting at 5, 6, 7 and 8 pm:
* Thursdays, 5:00 - 6:00 pm, room 32 Loomis Lab
* Thursdays, 6:00 - 7:00 pm, room 32 Loomis Lab
* Thursdays, 7:00 - 8:00 pm, room 32 Loomis Lab
* Thursdays, 8:00 - 9:00 pm, room 32 Loomis Lab
You are registered for one of these (Space is limited, so go to the section for which you are registered.) Attendance at your Thursday evening problem session is obligatory. Show up on time to receive full credit. We’ll take 15% off the credit for each 5 minutes of being late. If you are late by more than 30 minutes you will not receive credit. You will be able to access the problem session materials through the course schedule page.
Homework is an essential part of this course. The homework to be done will generally be assigned (and made available on line) at the end of the each Tuesday lecture and will cover the lecture material of that week. (unlike previous semesters, HW is not broken into parts A and B) I will collect your solutions at the beginning of lecture one week later. Please hand in your HW with the assignment stapled as a cover sheet on the front. You may also place your completed homework in the yellow PHYS 326 box located at the beginning of the second floor "Interpass" in Loomis, but it must be in the box by 11:00 am on the Tuesday that it is due to receive full credit. Late work will be marked down by 15% each day that it is late and will not be graded if it is more than one week late. If you do hand in your HW late, email the graders to tell them when you did so, otherwise it will be assumed to have been deposited just before the grader checked the box. I don't object to people working on the homework problems together as long as the work that you hand in for grading is your own. I strongly recommend that you thoroughly struggle with the problems yourself first. You'll learn more this way and you'll do better on the exams when you're on your own. Trust me on this one.
You will be able to access the homework assignment through the course schedule page in case you do not get it in the lecture.
There will be very short "miniquizzes" to be done in the last 5 minutes of each lecture. They will not be graded except as a check on attendance for cases of borderline course grades.
There will be two (probably in-class) midterm exams and one final exam. Dates will be announced. Please check the course calendar for full details.
Office hours are during the following times and in the following locations (watch for changes):
* Richard Weaver Tuesdays & Thursdays 12:30 to 1:00 4115 Eng Scis Building
* Po-Yao Chang HW grader Mondays 2:30-3:30 279 Loomis
NB Monday 9/2 is Labor Day, so the first week's Monday office hours are held on Friday 8/30
Your course grade will be based on your homework (~35%), exams (~15, 15 and 30%) and participation in Thursday problem sessions (~5%). There will be two midterm exams and a final exam.
The giving of assistance to or receiving of assistance from another person, or the use of unauthorized materials during University Examinations can be grounds for disciplinary action, up to and including expulsion from the University.
Please be aware that prior to or during an examination the instructional staff may wish to rearrange the student seating. Such action does not mean that anyone is suspected of inappropriate behavior.
Unless a problem states otherwise, you are not to use any calculating devices or symbolic manipulation tools in any of your work. No calculators, no computers, no slide rules. And no use of electronic search tools to find material relating to solutions to problems you are working. I will only permit paper and pen, and information you can find in textbooks and reference works such as calculus texts or tables of integrals and special functions. You are on your honor to hold to this.

Challenge: 1) What determines the speed of the chain? 2) What determines the height of the arc? answer 1) I think v = √gHeight above floor, 2) I don't know.
