1st order modelling 1 - mass-damper systems

[@JulesManson]

I am using these tutorials to refresh a course on Modeling and Design of Dynamic Systems that I took about 25 years ago. I didn't finish college back then but now I am determined to go back to CSULB and finish what I started.

Well, 25 years ago I finished mechanical engineering but the lesson of control systems was not required. Now, I study aeronautical engineering where this lesson is obligatory. So first I will look at all of Mr Rossiter videos and also his pdfs.Then I will have to solve lots of exercises from lots of books.

Is it true that friction will keep increasing with velocity for all values of velocity?

[@komodo961]

Shouldn't the velocity w at 6:20 be in the opposite direction?

komodo961 Sorry I cannot see a mistake in what I have done. damping force is based on difference in speed of the two ends.Anthony

[@komodo961]

John Rossiter Just realised my mistake, the velocities are indicated in the positive direction of their vectors, I was assuming it meant the direction of the left end of the damper, totes hilar

Friction is Constant * Force. but v is not force (velocity).????

I also dont understand this

audio is very bad.
