Great collection of papers

[Roy]

All,

Thanks for the wonderful repository of papers! I have been looking for
some of these for a while.

I've uploaded a few more for the collection:

* 1989 - Storch and Gates - Motivating Kanes Method for Obtaining EOM
for Dynamic Systems.pdf
(thematically similar to the 1992 Lesser, but simpler and much
shorter. I also have the Scott paper that this one is based on)
* 2000 - Baruh - Another Look at the Describing Equations of
Dynamics.pdf
* 1990 - Huston - Multibody Dynamics Formulations via Kanes
Equations.pdf

For those who might be interested, the Kane & Levinson Dynamics text
is available for download here:
http://ecommons.library.cornell.edu/handle/1813/638

I am looking forward to using PyDy, as soon as I can free up some time
in my schedule.

p.s. I'm looking for J. G. Papastavridis. A panoramic overview of the
principles and equations of motion of advanced engineering dynamics.
ASME Applied Mechanics Reviews, 51(4):239–265, 1998. Does anyone have
a copy?

Thanks for the papers!

Cool, let us know if you have any questions about pydy.

Roy,
Thanks for the papers! I'll see if I can track down the paper you
are looking for. UC Davis doesn't have a subscription to that journal
but I know some people who might be able to get it for me.

Thanks Luke, and Ondrej.

I will have lots of questions. The only thing I know about Python is
that it was named for Monty Python. I want to learn the language
anyway, for another project.

Which version of Python do I need? Can you recommend a good reference,
either on-line or a book? I do know C, if that helps.

Roy,

Without knowing anything about what you want to do with python, I might suggest installing the Enthought distribution.  They have a 32-bit "academic" version available for many platforms that can be downloaded for free (it's what I use):

http://www.enthought.com/products/edudownload.php

I think this is a pretty good way to get your feet wet because: (A) the enthought diistribution has a fairly complete set of packages for those interested in scientific calculations and (B) it makes installation pretty easy. 

I think your knowledge of C programming will be of great benefit.  First, you already understand the fundamentals of programming. Second, python utilizes many C libraries. Third, I think you will appreciate how Python, in many cases, makes it easier to write code as compared to C. 

There are plenty of good resources to help you get started.  Here are just a few freely available tutorials/ebooks:

http://www.diveintopython.org/
http://www.tramy.us/numpybook.pdf
http://docs.python.org/tutorial/
http://wiki.python.org/moin/BeginnersGuide/Programmers

Of course, it possible to obtain most other books via bittorrent or rapidshare. 

I might suggest coding something in python that you already have in C.  It's a good way to see the differences between the languages and will force you to learn the components of the language that are of most use to you first. 

Just my two cents,

Thomas
