Validated against published standards

Every active check is guarded by a hand-computed benchmark derived from the published clause equations.

Scroll through the real calculator workspaces.

Follow each live workspace from inputs and dimensioned schematics through the governing result and sourced code checks - every demand, capacity, utilisation, and assumption visible. Swipe or use the tabs to preview every calculator.

One growing catalogue of in-depth calculators.

Each one does a whole job end to end, rather than a single formula you would still have to assemble a calculation around.

Follow one number all the way down.

Every computed check carries its own derivation and the clause it came from. This is one of them, taken straight from the free lifting-lug example, with nothing rounded for the page.
