How to use this tool

  1. Enter every input in the labeled units; use measured or independently specified properties.
  2. Check the stated model assumptions before calculating.
  3. Interpret the output as a model estimate and verify it independently for the intended application.

{
  "width": 0.15,
  "height": 0.3,
  "flange": 0.02,
  "web": 0.01
}

Accuracy and scope

Ideal sharp corners; not a standard rolled-section lookup or local-buckling check. Educational engineering estimate only; not structural or safety certification, equipment selection, or operating recommendations.
