The deflection of a beam under load may be measured using a dial gauge for example but may also be calculated.

The equation opposite gives Deflection (Δ) of a simply supported beam loaded in the centre.

Where:

  • W = Load
  • L = Span
  • E = Young's Modulus ( - a measure of how stiff the materials is)
  • I = Moment of Inertia ( - a measure of the capacity of a cross section to resist bending)
