Engineering Calculators
Free engineering calculators for mechanical, structural, and hydraulic analysis. Calculate torque, stress, beam deflection, Young's modulus, friction loss, and head loss with standard engineering formulas.
Torque Calculator
Calculate torque from force and distance, or convert between torque units (lb-ft, N·m, lb-in). Includes bolt torque reference tables.
Stress Calculator
Calculate mechanical stress from force and cross-sectional area. Supports tensile, compressive, and shear stress calculations.
Beam Calculator
Calculate beam deflection, bending moment, and shear force for simply supported and cantilever beams with point and distributed loads.
Young's Modulus Calculator
Calculate Young's modulus (elastic modulus) from stress and strain. Includes material property reference tables for common materials.
Friction Loss Calculator
Calculate friction loss in pipes using the Hazen-Williams or Darcy-Weisbach equation. Essential for plumbing, fire protection, and irrigation design.
Head Loss Calculator
Calculate hydraulic head loss in pipe systems. Accounts for pipe diameter, length, flow rate, fittings, and pipe material roughness.
