Finite Element Anaylsis
This is a very cool feature on most 3D modeling softwares where you can apply forces to objects you have modeled to better understand your stress distribution and how much load your parts will experiences. The only downside is that it isn’t a real life reflection as FEA uses meshes to mimic your object to lower the calculation load, so its not a 1 to 1 replica of real life.

We can see from all the screenshots that the maximum amount of stress experienced from the model shows that all components are under the yield strength by at least a factor of 10 meaning that everything will hold.
