📊 Shear Stress Details

Parameter Value Unit

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
