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.

Try this example

{
  "hmin": 20,
  "hmax": 20.02,
  "smin": 19.98,
  "smax": 19.99
}

Accuracy and scope

Explicit limits only; negative clearance denotes interference. No ISO fit class lookup, contact pressure or assembly-force prediction. Educational engineering estimate only; not structural or safety certification, equipment selection, or operating recommendations.
