...and that I may but unless I get edumacated I would
always wonder. LD1 do you have a link to a calculator
or how are you calculating all those forces?
I just do the calcs with the calculator. Formulas is in my head. Those calcs are nice, but its also nice to understand how they get the numbers and I can usually get the answer quicker than searching and pulling up one of those like you linked.
Ex: your 3.5" cylinder, first we must find the square inches of the piston. Formula for area of a circle is pr x r squared...
So the radius is 1.75", square that and we get 3.06" Now multiply that by pi and you get 9.62 square inches of piston surface.
With 2400psi applied, you get a force of ~23,000lbs
Now for the angle part. It is simply the sin of the angle times the force. So in your case of 25 degrees, it would look like sin(25) x 23000= vertical force.
Its actually not that complicated because there really isnt as many steps as it seams. its all continuous on the calculator.
Key in 1.75, hit the square button, hit times pi, times psi and you have your force. Now without eveing having to clear, hit times 25 and the sin button then = and you have your answer.
Figuring the dump angles gets a little more complex though, have to use the law of cosines formula
