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

{
  "radius": 200,
  "initial": 10,
  "final": 8,
  "width": 100,
  "pressure": 200
}

Accuracy and scope

Small-draft geometric approximation; mean pressure is supplied, not inferred from material; spread and roll flattening omitted. Educational engineering estimate only; not structural or safety certification, equipment selection, or operating recommendations.
