How FEA Helps You Trust a Design
FEA turns I think it is strong enough into here is the factor of safety — and filters bad designs before you cut metal.

Finite Element Analysis (FEA) splits a part into small elements and solves how each one deforms under load. It turns a guess into a number: the factor of safety.
What FEA gives you
- Where stress concentrates
- How much the part deflects under load
- Whether the safety factor meets your target
- A comparison of design alternatives before you cut metal
FEA is not a replacement for testing — it is a filter. You simulate five designs, build one, and test it. That is faster and cheaper than building and breaking five.
