Engineer Calculators

Engineer Calculators groups tools by discipline, quantity and application, showing the equation beside each model. Its examples distinguish balanced three-phase power from DC power, and central-point-load beam deflection from a general beam problem. The three-phase example uses voltage, current and power factor; the listed equation is √3 × line voltage × line current × power factor. Other entries identify useful bounds such as steady heating, dry ideal-gas air density, pure shaft torsion and welding arc energy before process-efficiency correction. The public library is free without sign-up. Keep those model labels with copied results rather than applying a simple relationship to a different physical system.
