To find the bending stress of a square beam, you can use the following equation: σ = 6 × M / a³. Say a square beam has a side measurement, a, of 0.10 m and experiences a 200 N·m bending moment. Substituting these values into our square beam bending stress equation, we get:
σ = 6 × M / a³
σ = 6 × 200 N⋅m / (0.10 m)³
σ = 6 × 200 N⋅m / 0.001 m³
σ = 1,200,000 N/m² = 1,200,000 Pa
σ = 1.2 MPa Read more
