Euler-Bernoulli beam theory
Controls
Presets
Euler-Bernoulli theory relates a beam's deflection and internal moment to its load, span, and flexural rigidity EI. Deflection grows with the cube or fourth power of span, which is why doubling a span is far worse than doubling the load. Educational tool — not a substitute for a stamped structural design.

Max deflection1.30 mm
Max moment12.5 kN·m
Span/deflectionL/3840
Governing equation
Reading this result: At L/3840 this beam clears the usual L/360 serviceability limit, so strength (not deflection) is likely to govern the design.
