Calculate shear stress, force distribution, and safety factors for various loading conditions
📐 Shear Stress Formulas
τ = F/A (Direct Shear)
τ = Tr/J (Torsional Shear)
τ = VQ/It (Beam Shear)
τ = G × γ (Hooke's Law)
τ = shear stress, F = force, A = area, T = torque, r = radius, J = polar moment, V = shear force, Q = first moment, I = moment of inertia, t = thickness, G = shear modulus, γ = shear strain
💡 Tips
- Shear stress acts parallel to the surface
- Maximum shear stress occurs at 45° to principal stresses
- For ductile materials, shear strength ≈ 0.6 × tensile strength
- Safety factor should be ≥ 1.5 for normal loads
- Shear stress distribution varies with cross-section shape
- Consider stress concentrations at geometric discontinuities
