Classical mechanics iii

Lectures: 2 sessions / week, 1.5 hours / session

Recitations: 1 session / week, 1 hour / session

You must complete 8.223 Classical Mechanics II with a grade of C or better before taking this course. 8.03 Physics III: Vibrations and Waves is also recommended as a prerequisite, although it is not required.

This course covers Lagrangian and Hamiltonian mechanics, systems with constraints, rigid body dynamics, vibrations, central forces, Hamilton-Jacobi theory, action-angle variables, perturbation theory, and continuous systems. It provides an introduction to ideal and viscous fluid mechanics, including turbulence, as well as an introduction to nonlinear dynamics, including chaos.

Goldstein will serve as the main text for the majority of our material. However, we will also cover material that is not in Goldstein, in particular in our discussion of fluid dynamics and chaos. For the latter, there will be assigned readings from other sources.

For additional reading you may consider some of the following texts:

Landau, L. D., and E. M. Lifshits Fluid Mechanics. Butterworth-Heinemann, 1987. ISBN: 9780750627672. [Preview with Google Books]
Their first three chapters cover the material for our introduction to fluid mechanics. We will only use the third chapter for our discussion of viscosity.

Symon, Keith R. Mechanics. Addison-Wesley, 1971. ISBN: 9780201073928.
We will use a chapter from this book for reading material on non-viscous fluids.

Strogatz, Steven H. Nonlinear Dynamics and Chaos: With Applications to Physics, Biology, Chemistry, and Engineering. Westview Press, 1994. ISBN: 9780201543445.
An accessible yet detailed discussion of non-linear dynamics in both differential equations and iterated maps.

Landau, L. D., and E. M. Lifshits. Mechanics. Addison-Wesley, 1960.
Used for Classical Mechanics II and hence useful here for review.

A useful reference at a somewhat lower level than Goldstein, may be clearer for some topics.

Problem sets are an important part of this course. Sitting down and trying to reason your way through a problem not only helps you to learn the material deeply, but also develops analytical skills fundamental to a successful career in science. We recognize that students also learn a great deal from talking to and working with each other. We therefore encourage each student to make his / her own attempt on every problem and then, having done so, to discuss the problems with one another and collaborate on understanding them more fully. After any discussion, the solutions you write up and submit must reflect your own work.

There will be a two–hour midterm and a three–hour final exam.

Grades will be determined by a weighted average of:

The faculty may also take into account other qualitative measures of performance such as class participation, improvement, and effort.
