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

{
  "force": 10000,
  "l1": 1,
  "a1": 0.001,
  "e1": 200000000000,
  "l2": 2,
  "a2": 0.002,
  "e2": 100000000000
}

Accuracy and scope

Two concentric segments with ideal joint transfer and no intermediate applied force. Educational engineering estimate only; not structural or safety certification, equipment selection, or operating recommendations.
