Title: Impedance visualized (video)
Post by: Mecanix on September 12, 2020, 11:17:03 pm
All those tech talks from modern technicians & other engineers when asked "what is impedance", I have yet came across anyone who explained/shown it better.

I was thinking about this the other day while pushing the boy on a swing.

Once moving it is far less effort to swing by pushing high up on the chain than by short shoves.

Must be due to the harmonics of the energy being moved from arms to swing.

You can also push at twice the frequency if you pull push up and down, rather than front to back...

My god lol Was passed to me on StackExchange yesterday by someone who have a great talent in explaining things. Thought it was a creative way, if not the best, to visually represent the concept and dared to be the first to share The Exclusive! Yea that vid/demonstration/contrib is gold, kudos Shive
