Both calculators run independently — change the inputs on either side to compare results.

Beam Deflection Calculator

Calculate the maximum deflection of a simply supported beam under a point load, uniformly distributed load (UDL), or end load using standard Euler-Bernoulli beam theory. Use it to size beams in structural design or to verify deflection stays within serviceability limits (typically L/250 or L/360).

Column Buckling Calculator

Find the safe critical buckling load for a structural column using Euler's formula with a factor of safety. Essential for structural engineers designing steel columns, posts, or any slender compression member.
