Engineering Calculators
Interactive calculators for mechanism and machine design. Change the geometry, move a slider or drag a point, and every result and chart updates instantly. Each tool explains what its results mean and states clearly what its model covers.
Suspension kinematics calculator
Double wishbone and McPherson front suspension: camber gain, roll centre, track change, KPI, scrub radius, caster, trail, anti-dive, bump steer and roll steer, in wheel travel and body roll. Front, side and isometric views; editable geometry; results checked against an Autodesk Inventor kinematic model.
For: Formula Student teams, kit car and off-road builders, engineering students.

Tools for lifting equipment and hydraulic mechanisms are in development, starting with hydraulic scissor lift tables: actuator force, stroke and cylinder sizing.
How the calculators are built
- Engineering first: every model is derived from mechanics and checked against an independent method or a CAD kinematic model before publication.
- Clear limits: each calculator states what its model includes and what it does not, so results are used for what they are: concept and learning tools, not a replacement for full design analysis.
- Explained results: every result has a short explanation of what it means and how it affects the design.
