Guide to Structural Calculators

This hub covers the working maths behind load-bearing and rotating parts: beam analysis, section properties, stress and material behaviour, reinforced-concrete and retaining-wall design, shafts and gears, fasteners, welds, hydraulics, heat transfer and workshop cutting. It's used by mechanical and structural engineers, drafters, fabricators, machinists, welders and students who need a quick check before committing to a full-model or code calculation.

Beams: reactions, stresses and deflection

Start with the beam that matches your supports (simply supported, cantilever, fixed-fixed or overhanging), use beam reaction for support loads only, and step up to the combined shear-moment-deflection tool when you need the full picture; check the result against a serviceability limit.

Section properties and stress states

Second moment of area and section modulus feed the bending, shear and buckling checks; use Mohr's circle or von Mises when you have combined stresses, and material tools like Young's modulus and elastic constants to supply the inputs.

Second Moment of Area Calculator Section Modulus Calculator Bending Stress Calculator Shear Stress Calculator Euler Buckling Calculator Stress & Strain Calculator Mohr's Circle Stress Calculator Von Mises Stress Calculator

Column, member and fatigue checks

Use slenderness and Euler buckling for compression members, the combined axial-and-bending check for members carrying both, and stress-concentration and fatigue tools when the concern is cyclic loading or notches rather than a single static load.

Reinforced concrete, foundations and retaining walls

Group your job by element: beam flexure/shear and column capacity for members, slab and footing tools for horizontal elements, and the earth-pressure and wall-stability set when you're checking retaining structures for overturning or sliding.

Shafts, drives, fasteners and welds

For power transmission chain your way through shaft power/torque, gear ratio and pulley-belt sizing; for connections pick the bolt tool that matches your failure mode (torque, tensile area or shear) and use the weld throat and volume tools for welded joints.

Workshop, hydraulics and thermal

Everyday shop maths for fabricators and machinists: material weights, cutting speeds, bend and tap sizing, hydraulic cylinder force and speed, and quick heat-transfer or cycle-efficiency checks for thermal jobs.
