How the formula works
τ = F / A | τ_max = (4/3) × (F / A) for circular | τ_avg = F / A for rectangular
- τ (Shear Stress) = Force ÷ Area (MPa)
- F (Shear Force) = Applied force (Newtons)
- A (Area) = Cross-sectional area (mm²)
- Rectangular = Uniform shear stress distribution (τ_avg = F/A)
- Circular = Parabolic distribution (τ_max = 4/3 × F/A)
- Safety Factor = Applied to shear strength for design
- Material Shear Strengths: Steel ≈ 400 MPa, Aluminum ≈ 200 MPa, Copper ≈ 150 MPa, Wood ≈ 10 MPa
