MechanixCalc
Professional mechanical engineering calculations — all domains, one suite.
AI engineering assistant —
built into every tool.
Not a generic chatbot. The assistant sees your exact design — your numbers, your material, your results — and gives advice grounded in the standard.
- "Why is my SF 1.2?" — it already knows your Von Mises, Sy, and fatigue limit.
- Cites DIN 743, ISO 281, AGMA — whichever standard governs your tool.
- Available on all 48 tools. Shaft, bearings, gears, fatigue, fluid systems.
Why is SF so low?
Von Mises is 387 MPa against Sy 900 MPa — that's fine. The issue is the Goodman fatigue limit: Se = 193 MPa with σm = 35 MPa and σa = 165 MPa gives nG = 1.2. Increase seg 2 to Ø70 mm → nG ≈ 1.8.
What material would help?
Drag-and-drop hydraulic & pneumatic circuits. ISO 1219-1 symbols, multi-sheet, cloud save & share links.
Piping & instrumentation diagrams per ISA 5.1. Instrument lists, line designation tables, print-ready A3.
IEC 60617 control diagrams with rung numbers. Motor & terminal lists, wire tables, share links.
