Piston dimensioning

Are you sure that piston model is serious?
I ask you both because the odds 399 and 99 mm know how to grip me for the bottoms, and because by personal experience I tell you that I have never seen a hydraulic piston so done. . .
what leaves me perplexed are the 3 caves that so to the eye seem identical; Typically in a double effect cylinder piston you have a central guide ring whose quarry has a higher width than the side seals, or you use a central bidirectional seal with 2 side guide rings, but never saw 3 identical cables
then the fact that it uses spheroidal cast iron. . .
I do not argue about the veracity of the size or the piece itself,
I'm just wondering if my calculations are good
I'm sorry, you're an engineering student, have you ever heard of evenly paid load and momentum? or, complicating things a little bit, under pressure plates?

is a uniformly distributed load beam subject to a max sigma equal to the pressure generated by the distributed load? Think about this, and then go back to your piston.
That's the kind of suggestion I was looking for. . .
Thank you! ! ! ! !

the odds 399 mm of the cylinder diameter is definitely given by the construction design of the piece and not by the theoretical calculation data. Usually it is the diameter of the shirt that is right, the piston is less than 1-2 mm to allow mounting... with the seals that then finds itself in the correct diameter.
