Re: Forced damped pendulum

We're (sloppily) assuming a damping force that is linear with angular velocity - just to make the solution a bit more accessable to my student who only has 1 year of High School calculus under his belt. To be more "precise" it should go like angular velocity squared.

What type of damping do you assume? If you have a damping force proportional to the speed, it is a standard problem with an easily available solution. If you deal with a CONSTANT damping force, i.e. a constant force always in a direction opposite to the velocity, then it becomes a fun problem to deal with. Can be done analyticlly too. Let me know which it is you are dealing with.
