AW: [DML] Re: 1 BAR = 14.7 PSI

["Elvis Nocita" <elvisnocita@xxxx>]

Guys,
I was offline a few days, therefore this late response.

The refillable struts have almost the same size as the original ones.
They can not be recharged with an ordinary air compressor like most
people have in their garage. It needs something with a little more
kick. A pump for air pressurized guns ! (I know, you american guys only
play with real guns, but in some countries this is not allowed...)

A regular compressor only makes about 8-12 Bar, we are talking about 170Bar
!
The piston has an area of about one square centimeter

p=f/a -> f=p*a = 170bar * 10E-4 m² = 170 * 10E5 N/m² * 10E-4 m²
= 170 * 10N = 1700N
(f=p*a -> force = pressure * area -> simple, isn't it ?)
Now this is 1700N instead of 1200N of the original Struts. Why ?
Because I only assumed that the effective area is 1 square cm. I haven't
measured it ! If it's a little bit less you will have your 1200N.

A temperature compensation would be a great idea but hard to realize.

This link shows how the struts look inside. Sorry, in german !
