Do Hood Springs Wear Out? Topic is solved

Springs only determine the resonant frequency, the won’t stop unless you spray them water...dampening them

( In keeping - Kind Of - with the water theme )

Oh, c’mon! That’s a red herring...
The ringing will stop eventually.
Those pesky laws of thermo-dynamics.

It’s still early here... That’s all I’ve got.

FWIW - They look like this:

Those look worn out. ( great pic)

Still have that pesky springing in my ears but yes, nice pic!

That's why I had to pull the hinge stops and stand it straight up!

Maybe it’s a seasonal thing ??

Hi,

Hey i know you were only joking, but tapping the spring would actually cause it to resonate for maybe a second or two, and if that frequency was picked up with say an o'scope and mic, that could be used to determine the ageing perhaps.
Of course we'd need a reference to the spring when it was new, which i am not sure would be too easy to get.

Ok, all seriousness OFF...
I solved the required ODE, and the result was:
f(t)=Old_Azz_Car

Hi,

Oh yes, thanks for the pic. So that's where they were hiding.
Now i can see that all i have to do is add a few rubber bands

Not so fast, with them hidden under the fender you'll need PDEs (t, x, y, z)!
