Engineering Dynamics

Come see more videos, simulations, and demos at our website: EDUCADIA.ORG
These 60 short videos will walk through the content of an engineering dynamics course. They should provide a good intuitive 'feel' for the principles: this feel is the starting point for careful and rigorous analysis, as well as insightful creativity. They are intentionally 'rough', as I think students (myself included) learn best when we get to think through a problem with the presenter. However, I also strive to make our explorations of the material clear. These videos follow the text of Ruina-Pratap (an excellent text), and that is where I get the numbering convention.

BASIC INFO ON VIDEO PURPOSE:

These videos are being used at Cornell (my alma-mater) S14 as supplemental material for their Dynamics course. They are not meant to stand alone-- rather, they are meant to go hand-in-hand with trained instruction and group discussion / projects.




BASIC INFO ON ME:

I am a Professional Engineer, engineering consultant, and teacher, amongst other things. I believe that this type of medium is part of a model that has the potential to transform engineering education. So, I'm making these videos to test my theory. I have worked with seasoned educators and subject experts to create high-quality videos. I'm doing this because I love it (no, I'm not paid) and I believe content like this should be free. Please let me know if you find any mistakes or confusion, either of omission or commission. I can't emphasize enough that these modules are the beginning of an iterative process. I want to also express tremendous gratitude to Andy Ruina for his continued input, criticism, and support of these videos.

IF YOU ARE HAVING TROUBLE WITH THE MATH:

In section 9.1, we cover basic differential equations. If this is giving you some grief, the material is covered in Khan Academy: Their videos should give you an elementary, intuitive understanding of the concepts:

1. For trouble with the basic setup of diff. eq., go to these videos:
a. http://www.khanacademy.org/math/differential-equations/fi....
b. http://www.khanacademy.org/math/differential-equations/fi...

2. For trouble separating the variables (the first step in actually solving the eqn.):
a. http://www.khanacademy.org/math/differential-equations/fi...
b. http://www.khanacademy.org/math/differential-equations/fi...


In section 9.3, we cover second order differential equations. If this is giving you some grief, the material is covered in Khan Academy, from http://www.khanacademy.org/math/differential-equations/se... :

1. For trouble with basic 2nd order O.D.E., watch the 'Linear Homogeneous Equations' category, videos 1-4.

2. For studying how to solve unusual driving forces (including periodic forces), watch the 'Method of undetermined coefficients' category, videos 1-4.

3. For studying complex roots of the characteristic equation, watch 'Complex and repeated roots of characteristic equation', all 5 videos. This isn't necessary yet, but you will need it in later engineering studies.
