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

{
  "outer": 0.1,
  "inner": 0.05,
  "force": 1000,
  "mu": 0.3,
  "surfaces": 2
}

Accuracy and scope

Steady uniform-wear model; excludes thermal capacity, fade, wear rate and transient engagement. Educational engineering estimate only; not structural or safety certification, equipment selection, or operating recommendations.
