Frequently Asked Questions (FAQ)
What is the Beam Deflection Calculator (Uniform & Center Load) and how does it work?
Civil and structural engineering tool. Evaluates bending stiffness of steel or timber sections based on Elastic Modulus ($E$) and Moment of Inertia ($I$).
How do I use this Beam Deflection Calculator (Uniform & Center Load)?
Enter Central Point Load ($P$ in Newtons - N). Enter Beam Span Length ($L$ in meters). Select Material Elastic Modulus ($E$, e.g. Steel = 200 GPa). Enter Cross-Section Moment of Inertia ($I$ in cm⁴). View Calculated Maximum Deflection ($δ_{\max}$ in mm).
What mathematical formula is used in this calculation?
Center Maximum Deflection δ_max = (P * L³) / (48 * E * I). 1 GPa = 10⁹ Pa.
