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

{
  "modulus": 200000000000,
  "alpha": 0.000012,
  "change": 50,
  "area": 0.001
}

Accuracy and scope

Perfect axial restraint, uniform temperature, constant properties and elastic response. Negative output indicates tension. Educational engineering estimate only; not structural or safety certification, equipment selection, or operating recommendations.
