I have an object that is spring loaded. If someone lets go of the object it will spring back quickly, potentially hurting someone.
I want to dampen how quickly the object springs back.
I am calculating the velocity at the orifice of a pneumatic cylinder using Bernoulli's equation.
I need help determining the pressure inside the cylinder (P1).
The pressure inside the cylinder is not simply F/A due to the presence of the orifice.
When applying Bernoulli's equation, I assumed...

if it can't determine buckling, I don't see the benefit it has over Solidworks.
The only benefit I see is that it might be quicker than SW to model a large structure.
I currently use Solidworks Simulation to analyze A-Frame capacity (See picture). My question is,
(1)Should I purchase RISA 3D or Solidworks buckling addon to analyze the stability of the A-Frame?
(2)Does RISA provide additional insight to whether or not the A-Frame can support the load?
If...
SolidWorks says the collar is free to translate and rotate. I'm not sure why the shaft isn't preventing rotationhttps://files.engineering.com/getfile.aspx?folder=920315f2-e8fa-4414-8573-75ad9881bb3b&file=Capture.JPG
My "collar" isn't properly constrained apparently. I'm getting a message saying excessive displacements.
The excessive displacements isn't due to the torque of 1 in-lb.
See picture of message & my constraints...
I'm using solidworks to simulate. (I'm new to solidworks simulation and FEA in general)
Problem
1. Ends of shaft are fixed.
2. torque is applied to collar.
3. I want to determine the stress on the collar and shaft when torque is applied to collar.

what do you mean by "I then treated the solid body as a beam." ?
Look at picture, steps.JPG. The 2nd step I clicked "treat as beam"
Are you using the FEA embedded in SW CAD or the SW FEA ?
SW FEA
What do you mean "My new approach is to simulate as a solid body rather than beam. The ends...
My new approach is to simulate as a solid body rather than beam. The ends will be fixed.
For a fixed beam on both ends
Max Moment = wL2/12
Max Displ. = wL4/(384EI)
For a simply supported beam
Max Moment = wL2/8
Max Displ. = 5[wL4/(384EI)]
With these formulas, I'll deduce the max stress and...

The steps I took are outlined in the picture.
To answer your question with my limited knowledge: "are you modelling with beam elements or 3D solids ?"
I modeled a solid body (the tube and bar is one solid body). I then treated the solid body as a beam.
I hope this answers your...

I modeled the two parts as one solid body.
I then treated the solid as a beam.
I tried another test.
I removed the solid bar and simulated the tube only. The displacement and stress didn't change
I then added the bar back and looked at the simulated model. As you can see from the...
I'm varying the round bar length inside the tube to see how it effects the simulated results.
In both instances shown in picture, the results were the same.
I expected the displacement and stress to be less in the bottom configuration (see...
I simulated supported beam.
I wasn't sure how to configure a simply supported beam in solidworks (I'm new to FEA).
I figured it out though.
Thanks for the input everyone.
A reel is loaded onto an axle. I want to determine if the tube portion of the axle can support the weight of the reel.
I'm not sure what boundary conditions to apply to the ends. Can someone help me with the boundary conditions...
