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)
