So, RB1957 pushed me in a direction I think that solved my issue. Where i have ended up is this.
1) Determine how much compression force is require on the assembly.
2) Determine how much vertical compression of the o-ring is required.
3) Determine what total angle the linkage has to move thru to...
So, that .ipt file is the simplified version of this. Ultimatley, that calculator is for us to size linkage assemblies/cylinders. This attached image shows what I am really doing. So, what I am trying to figure out, is what is the point at which the cylidner can't push past TDC (after the lower...
I have created a toggle link force calculator in Inventor. I got the equations from https://www.engineeringtoolbox.com/toggle-joint-d_2077.html and used the arms of UNEQUAL lengths set up. Now, the issue we are are trying to figure out is what is the actual force we can apply without stalling...
