How to use this tool

Enter every input in the labeled units; use measured or independently specified properties.
Check the stated model assumptions before calculating.
Interpret the output as a model estimate and verify it independently for the intended application.

Try this example

{
  "radius": 0.05,
  "rod": 0.2,
  "angle": 60,
  "omega": 100
}

Accuracy and scope

Rigid inline crank-slider with constant angular speed and no offset or bearing clearance. Educational engineering estimate only; not structural or safety certification, equipment selection, or operating recommendations.
