>Understanding Beam Deflection and How to Calculate It
Beam deflection is a critical concept in structural and mechanical engineering. It refers to the degree a beam bends or deforms when subjected to external forces such as loads or pressure. Knowing how much a beam will deflect helps engineers design safe and stable structures like bridges, buildings, and machinery.
This free online Beam Deflection Calculator allows you to estimate deflection for simply supported beams under a central point load. All you need are four key parameters:
- Beam Length (m): The total span between supports.
- Load (kN): The force applied at the center of the beam.
- Young’s Modulus (GPa): A material property indicating stiffness.
- Moment of Inertia (cm⁴): A geometric property based on cross-sectional shape.
The formula used is: δ = (P × L³) / (48 × E × I), where P is the load, L is the beam length, E is Young’s Modulus, and I is the moment of inertia.
This tool is especially helpful for students, educators, and professionals working in civil, mechanical, or structural engineering. Whether you're designing a steel frame or analyzing bridge components, this calculator simplifies complex calculations and improves accuracy.
