Understanding Beam Deflection

Beam deflection is the displacement of a beam from its original position under a load. This calculator specifically solves for the maximum deflection of a simply supported beam with a concentrated load at its center. This is a common scenario in structural engineering.

Formula Used: `δ_max = (P * L³) / (48 * E * I)`

  • `P` is the applied load.
  • `L` is the length of the beam.
  • `E` is the Modulus of Elasticity, a measure of the material's stiffness.
  • `I` is the Moment of Inertia, a property of the beam's cross-sectional shape that determines its resistance to bending.
