Mechanism tools,
with the math showing.

Each tool gives you an instant closed-form preview with its residual on screen, the equations behind it, and a one-click path to the full MBSD solver for dynamics, diagnostics and export.

01 / SLIDER-CRANK

Slider-crank kinematics calculator

Stroke, slider velocity, rod angle and quick-return ratio for in-line and offset slider-cranks, with the equations behind them.

02 / FOUR-BAR

Four-bar linkage calculator

Grashof classification, rocker swing, transmission angle and coupler curves for any four-bar, checked live as you drag.

FULL SOLVER

Constrained dynamics in the browser.

The full app runs the open-source MBSD solver locally in your browser through Pyodide. No server and no install. The first load downloads the Python runtime once.
