What the calculator is for
Length, load, elastic modulus, I, and W describe a prismatic beam. Typical applications include early stiffness estimates for beams, brackets, and machine frames.

Set the inputs and run the calculation.
Load cases
Supports, load and deflection
Four basic cases show how support and loading determine deflection. θmax is intentionally omitted.

What still needs checking
Euler-Bernoulli theory assumes small deformation, linear-elastic material, and a slender beam. Shear deformation, self-weight, and stability failure are excluded.
