SIMPLE HARMONIC MOTION--help needed

Hello ,

i m looking for examples for simple harmonic motion,.. how does this theory apply in daily life?

I had go through the net

, i find that the examples given are the simple motion of the spring and pendulum. Any other examples on this?

I would very appreciate on your reply as this will really help me in my understanding in oscilliations

Many musical instruments produce their sounds by vibrations, which are combinations of simple harmonic motions.

What about the shock absorber of a car? You have a mass (m),spring (k) and damper(c/2m).

F=ma
Fs+Fd=my"

y"+(c/2m)y'+(k/m)y=0,<-this is damped HM

y"+(k/m)y=0<- this SHM the damper is not included

IC's: y(0)=K1 y'(0)=K2 <-these could be any values
