Welcome
to Physics 326: Intermediate Mechanics II The instruction for this course begins at 11:00
am on Tuesday, Aug 26, 2014 in 144 Loomis Laboratory of Physics (LLP). The
schedule (subject to change) can be found here.
General
Overview
The
format of the course is very like that of last semester's Phys 325. See below for specifics on HW and
exams and discussion. Phys
326 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.
Texts
*
Taylor, Classical Mechanics
* Marion and Thornton, Classical Dynamics of Particles and
Systems. The Fifth
Edition is best, but earlier editions are also fine.
(optional)
These books should be on reserve in
Grainger Library.
* A booklet of 256 pages constituting an edited version of
the lecture notes from last year is available at FedEx/Kinkos on Wright
Street in Champaign (if they run out let them/me know). Purchasing it is
strongly recommended but 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. Lectures
tend to be much more clear when you have skimmed the material before hand.
Online
access
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
rwiltfon@illinois.edu. You should always log out of the secure server at the
end of your session.
Lectures
Lectures
are held 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 at the course website after each class. The official notes will differ Ð
for example they will include the miniquizzes; also they will more closely
follow the sequence and material of the actual lecture - from those available
for hard-copy purchase at the beginning of the semester.
Problem
sessions
The
problem sessions will take place weekly (starting Aug 28). 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.
WeÕll 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. After class you will be
able to access the problem session materials through the course schedule page.
Homework
Homework
is an essential part of this course. The homework to be done will generally be
assigned (and made available online) at the end of the each Tuesday lecture and
will cover the lecture material of that week. Like last semester, HW is 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.
Quizzes
There
will be very short "miniquizzes" to be done in the last 5 minutes of
each lecture. They are graded only
for attendance, and constitute 1% of the course grade..
Exams
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

Grading
Your
course grade will be based on your homework (~34%), exams (~15, 15 and 30%) quizzes (1%) and participation in
Thursday problem sessions (~5%). There will be two midterm exams and a final
exam.
Academic
Integrity
The
giving of assistance to or receiving of unauthorized 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.
===========
The campus has asked us to read and be aware of the following general instructions for emergencies that may occur during classes. You should probably sign up for emergency text messages at emergency.illinois.edu
Emergency
Response Recommendations
The Department of
Homeland Security and the University of Illinois at Urbana-Champaign Office of
Campus Emergency Planning recommend the following three responses to any
emergency on campus: RUN > HIDE > FIGHT
Only follow these
actions if safe to do so. When in doubt, follow your instinctsÑyou are your own
best advocate!
RUN
Action taken to
leave an area for personal safety.
* Take the time now to
learn the different ways to leave your building before there is an emergency.
* Evacuations are mandatory
for fire alarms and when directed by authorities. No exceptions!
* Evacuate immediately. Pull
manual fire alarm to prompt a response for others to evacuate.
* Take critical personal
items only (keys, purse, and outerwear) and close doors behind you.
* Assist those who need
help, but carefully consider whether you may put yourself at risk.
* Look for EXIT signs
indicating potential egress/escape routes.
* If you are not able to
evacuate, go to an Area of Rescue Assistance.
* Evacuate to Evacuation
Assembly Area and remain until additional instructions are given.
* Alert authorities to
those who may need assistance.
* Do not re-enter building
until informed by emergency response personnel that it is safe to return.
ACTIVE THREAT:
* If it is safe to do so
run out of the building. Get as far away as possible. Do not go to the
Evacuation Assembly Area.
HIDE
Action taken to
seek immediate shelter indoors when emergency conditions do not warrant or
allow evacuation, such as for severe weather.
* Take the time now to
learn the different ways to seek shelter within your building before there is
an emergency.
* If you are outside,
proceed to the nearest protective building.
* If sheltering-in-place
due to severe weather, proceed to the identified Storm Refuge Area or to the
lowest, most interior area of the building away from windows or hazardous
equipment or materials.
ACTIVE THREAT:
* Lock or barricade your
area.
* Get to a place where the
threat cannot see you.
* Place cell phones on
silent.
* Do not make any noise.
* Do not come out until you
receive an Illini-Alert advising you it is safe.
FIGHT
Action taken as a
last resort to increase your odds for survival.
ACTIVE THREAT:
* If you cannot run away
safely or cannot hide, be prepared to fight with anything available to increase
your odds for survival.
