MechanixCalc

Standards-based mechanical engineering calculators that run in your browser.

MechanixCalc is a suite of 50 calculators across 9 domains - gears to ISO 6336, bearings to ISO 281, bolted joints to VDI 2230, shafts to DIN 743, pressure vessels to ASME VIII, welds to EN 1993-1-8, pipe stress to ASME B31.3, and 39 standards in total. Each tool names the standard it implements, shows the formula and a worked numeric example, returns a PASS / REVIEW / FAIL verdict, and exports a PDF report a reviewer can follow line by line. Where a panel uses an accepted simplified model instead of a citable standard, it says so.

On this channel: short demos of each calculator, worked examples, and how the numbers are verified.
