I = bh³/12 = 0.1 0.2³/12 = 6.667×10⁻⁵ m⁴. y_max = 0.1 m. σ_max = (20,000 0.1)/6.667e-5 = 30 MPa. Chapter 7: Beam Deflections (Double Integration and Superposition) Method: EI d²v/dx² = M(x).
Numerical solution: Let F₁+F₂=100 kN. Deformation equality: F₁ 1.5/(500e-6 100e9) = F₂ 1.2/(400e-6 200e9) → F₁ 1.5/(5e-5 1e11) = F₂ 1.2/(4e-4 2e11) → simplify → F₁/F₂ = 0.8 → F₁=0.8F₂. Then 0.8F₂+F₂=100 → 1.8F₂=100 → F₂=55.56 kN, F₁=44.44 kN. Formula: δ_T = αΔTL, thermal force = EAαΔT (if constrained). solucionario resistencia de materiales schaum william nash
Simply supported beam of length L=6 m with point load P=10 kN at midspan. Draw diagrams. I = bh³/12 = 0
A steel rail (α=11.7×10⁻⁶ /°C, E=200 GPa, A=6000 mm²) is stress-free at 20°C. If constrained at both ends, find stress when temperature rises to 50°C. Then 0
