Im sorry, i forgot to say that in my equations, "s" is a part of the circumference where the Torsion is being applied. x is the lengh of the cylinder, r the radius. It may be a correct way of thinking about it, but i don't see how this is going to help. Is γ⋅dx = r⋅dϑ the formula of an helix...

Hi all, In this article, page 7 - 3 there is a drawing of a Cylinder suffering Torsion. In the next page it says: ftp://www.bauwesen.fh-muenchen.de/Bauwesen/Konrad/Baustatik_1/Festigkeitslehre/kap07.pdf γ⋅dx = r⋅dϑ From my observations i come to tan γ=s/x ; tan ϑ=s/r ; therefore x⋅tan γ =...

I understand what you mean, i was confused, thanks a lot. I thought the fact that a Force acts in a surface means there is less pressure for the others to hold. That is of course not true.

The fact is that a Zylinder is built with 2 circles and 1 rectangle. But when i look for the formula that calculates the Force applied to one of the circles (Like Piston with compressed fluid work) depending on the Pressure, i find everywhere: F=p*ACircle, where A is the Area of that circle. My...

Hi, given an Hydraulic Cylinder with the Formula: F=p*A Why do we use APiston to calculate the Force in Work-Direction? Doesnt it suppose the "Potential Energy" of the compressed air just presses in that Area? Im pretty confused, sorry about the unconcrete question.

i knew it wasnt right, just to lazy to google another Word today... but thanks anyways. i will come to you with an interesting question next days, if you are prepared :)

lol, i scrolled the whole page looking for what i was missing until i got it

Yes, i meant point masses. Okay, that clears everything, thank you very much!

And sorry again but it cannot be both at the same time. You can get energy and give at the same time. The addition determines wheter you are losing, gaining, or remaining with the same energy.

Sorry but i don't think so. When you release an object it transfers its potential to cinematic energy. it doesn't win anything.

Hi everyone, first post here. Today i crushed into a question. I was going to write it down here, then i crushed into another one. Lets say we want to know the potential energy of a body relative to a center of gravity. I will refer to gravitys acceleration as "g" and to mass as "m". "k" will...
