Mechanical Engineering Calculations

AGMA / ISO Gear Calculator — Geometry, Full AGMA Strength (Bending & Contact)

Now includes full AGMA-style bending and contact stress calculations (K-factors, geometry factors I & J approximations, Cp elastic coefficient, allowable stress checks). All calculations show formulas, intermediate values and give options for user overrides. Notes: I and J geometry factors are calculated using AGMA/Levi approximations; for contract acceptance use AGMA 908-B89 tables or FEM validation.
