Readings and Homework, Fall 2018
ME 4730/5730, Dynamics

----    SUBJECT TO CHANGE, all semester long  ----
           ---- This page in progress on 10/28/2018  ----

Please read the Homework policy a few times, once before doing each of the first few homework assignments.
Assignments will be posted on Piazza.

Homework Solutions: TBD

Planned coverage (what you should know by the end of the semester)

Dynamics: Basic mechanics of 2D mechanisms by Newton-Euler, Lagrange or DAEs. Theory and practice

Basics: Ruina & Pratap (RP) The whole book (mostly review, but you should master all of it).

Topics which go a bit beyond many of the standard books

1) Using Matlab for simulations, plotting and animation.
2) Use of Angular Momentum balance to get equations of motion for complex systems.
3) Mechanisms (linked rigid objects)
4) DAE  (Differential Algebraic Equations) formulation of equations of motion

3D Dynamics: We will cover the core ideas of the 3D dynamics of a single rigid object.
