Structural analysis calculators for stress and strain, beam deflection, column buckling and second moment of area. Built on classical mechanics principles, these tools support static and fatigue analysis for mechanical components and structures.
Use this calculator to determine normal stress and shear stress in mechanical members. Normal stress (σ) results from forces perpendicular to a cross-section; shear stress (τ) results from forces parallel to a cross-section. Supports direct area input as well as circular and rectangular section helpers.
Use this calculator to determine axial strain (ε = l''/l), shear strain (γ = λ/l), and Poisson cross-section deformation. Given the original length, deformation, and Poisson''s ratio, it computes the transverse strain and the new cross-sectional area.
Use this calculator to apply Hooke''s Law for normal loading (σ = Eε) and shear loading (τ = Gγ), and to compute the elastic strain energy stored in a member (U = W²l/2AE). Includes material presets for common engineering materials.
Analyse circular shafts under torsion: compute shear stress τ from torque, torsion angle θ from shaft properties, shear stress directly from the angle using formula τ = Grθ/l, or convert power and speed to torque. Covers both solid and hollow cross-sections.
