Lectures: MWF 10:20  11:10. Room TBD. Mostly online. Click on Zoom (menu list at left. Password: dynamics)
Office Hours: (Online, at the course zoom link.)
 Andy Ruina: listed on his homepage

Work together? The course zoom link is always open. Think of it as a study room. Go there and hang out. Even if you are alone, someone may show up. Or, post on Piazza that you are there. If you know a better scheme for enabling students to work together, let us know.
GroupMe: There is a group chat you can join on groupme to more easily talk to other students about homework and coordinate meetings to study and work on homework together over Zoom. Here is the Link.
Questions or comments? Post them on Piazza. You would be surprised how many people also have your seemingly unique and obscure question. You can post anonymously, if appropriate. Use email for emergencies.
Prerequisites:

MAE 2030 (Engineering Dynamics for sophomores), or equivalent.

MATLAB. You need to be comfortable with Matlab already, or get up to speed quickly. How? Do all the tutorials in Pratap's book, or equivalent. Then use that book, or another, or google, for help with other things you need. You get to the skills you need the same way you get to Carnegie Hall.
 Matlab tutorial for those with no Matlab background: Saturday, Sept 5: 11 AM  1 PM. Use course Zoom link.

System Dynamics, MAE 3260, is not a prerequisite nor a corequisite for this class, it is listed to indicate a general level of mathematical sophistication.
Homework Due Fridays, at midnight. Peer grading of HW due Monday at midnight. Directions for peer grading will be posted. After the first week, you will have at least 6 days from when the assignment is given until it is due.
Course Components and Grades.
Assume all components scaled to about the same mean or maximum.

Exams, about 60%. Keeping 9 or 10 best of the 11 prelim and final exam questions. All exams are closed book, closed notes.

Prelims:
 1) Thu 08 Oct 07:30 PM Kennedy 116 , 3 problems
 2) Sun 08 Nov 04:00 PM Statler 185, 3 problems
 Final exam: date TBD, 5 problems

 Final project, about 20%: (includes your oral response to questions about your project);

Homework, about 20%: (after dropping the lowest few scores).
The median student, in both courses, will get a B or a B+ (to be determined). Those in 4730 will get bonus points so that they can get an equal course grade while still not doing as well on some of the difficult parts.
If we perceive that you have attended every lecture, taken all exams without giving up, do the final project, and spend at least 6 hours each week doing HW you are guaranteed a grade of at least B. If you can do all of the homework yourself, without help, you will probably get a B+ or better. If, additionally, you can reproduce all of the theory from the lectures and extend it slightly, you will probably get at least an A.
Read more of Andy's thoughts about grading, posted on the world wide web, here.
And, here is the grading scheme for a large course where laying out the exact letter of the law helps relieve some student anxiety.
Homework
Homework will usually be due Fridays at 11:59 pm. The homework that is submitted will make up the majority of the homework grade of each student. The rest will be determined by how well they grade their peers (see Peer Grading below). Students will submit the following.
 .zip folder will contain the following
 PDF, which contains all information:
 Scanned written work
 Necessary plots
 Code (so graders can leave comments/marks in specific places in it)
 All .m files written for the homework (code)
 A readme file briefly explaining how to run their code
 PDF, which contains all information:
 After homework due date, students will have 3 days to peer grade (due Monday 11:59 pm).
Peer "Grading"
Each student will critique the homework submitted by one of their peers each week. You will receive a peer grading grade correlating to how well you critique your peers.
Guidelines
 Leave many comments in the homework PDF, pointing out things that are wrong, unclear, incomplete, interesting, brilliant, ideas for improvement, etc.
 Download the PDF, leave notes/marks on it, reupload it as an attachment in a comment on Canvas.
 Leave one large comment answering the following
 Overall what is your impression of the homework, point out key things that are good and things that should be improved.
 You can leave this large comment on Canvas. You can also attach it as the first page you the markedup PDF you upload as well if you want.
 Answer these questions
 Were FBDs always used when needed, and always clear?
 Was vector notation and calculation always clear and grammatically correct (within the grammar of vectors, e.g., vector = scalar => bad)?
 Were principles stated general form before being used in the particular form needed for the problem at hand?
 For Matlab plots, were all the homework preamble rules followed (e.g., axis labeled and clear, 'axis equal' when appropriate).
 Overall, was the work clear and convincing? (see the homework preamble)
 Assume this student had infinite time, what would they have to do more of, or differently, to convince you that you could 99% trust their work?
Suggested Reading

There is no single book that covers this course material.

Matlab. Within the first month or so you should know everything in the Statics and Dynamics book by Ruina and Pratap. When you have mastered that, you know useful things. And if you don't master it, you will be at a disadvantage. Here are some MATLAB examples. Some more examples from Sophomore Dynamics'
Rajesh Bhaskaran Tutorial for Cornell Engineering Students 
Any book on Dynamics at a higher level than Ruina and Pratap (above), e.g.
1986_Beatty_Kinematics.pdf 2006_Beatty_Dynamics.pdf. Books by Beatty are the best/closest I have found.
Greenwood is closest in philosophy, but its organization is imperfect and it does not emphasize numerical solutions.
Synge & Griffith (pdf), a classic great book, not computational. This was Andy's book when he took dynamics as an undergraduate.
Bernstein (pdf), brand new, mathematically precise. Dennis was a costudent, with Andy, in linear algebra as an undergraduate.
O'Reilly, Oliver O'Reilly is now a Berkeley prof. But he first learned dynamics in an earlier version of this very course.
Moon, Francis "Frank" Moon taught this course for many years.
A. Rao, Anil Rao first learned dynamics in 2030 from Andy at Cornell.

Additional Resources
There are solutions for the homework problems assigned in previous versions of the course. These solutions were written by the students who took the course before and are by no means perfect. This semester, two students have volunteered to share their notes with the class. There are also notes from previous semesters as well. All of this can be accessed here.
