Mechanical Calculators
In development — coming soonMechanical calculators cover machine elements — the shafts, gears, springs, bearings, and fasteners that transmit motion and carry load inside a machine. This category is in development and no tools are published yet.
The planned tools follow the usual design references: Lewis and AGMA for gear tooth stress, ASME B106 for shafts under combined bending and torsion, ISO 281 for bearing life, and the Goodman criterion for fatigue under a mean stress.
Until then, nothing on this page is a working tool. The lists below show what the category will hold and which published calculators already overlap with it, so a visit here does not end in a dead end.
What This Category Will Cover
Planned tools. None of these are live yet, so they are not links.
Closest Tools Available Today
Published calculators that already answer part of a mechanical question.
Motor Torque Calculator
Calculate steady-state motor shaft torque in N·m or lb-ft from motor output power (kW or hp) and operating speed (rpm). Screen result as LOW, NORMAL, HIGH, or VERY HIGH.
Calculate nowHeat Exchanger Calculator
Calculate heat exchanger heat duty using overall heat transfer coefficient, heat transfer area, and log mean temperature difference (LMTD) in imperial or metric units.
Calculate nowFan Law Calculator
Calculate new fan airflow, static pressure, and brake horsepower using the three HVAC fan laws. Predict fan performance changes from speed, diameter, or density adjustments.
Calculate nowPump Power Calculator — Hydraulic, Brake & Motor HP
Calculate pump hydraulic power, brake horsepower, and motor electrical input from flow, TDH, SG, and efficiency.
