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.

Beam Deflection Calculator

Compute the maximum mid-span deflection of a simply supported beam under a uniformly distributed load (UDL) using δ = 5wL⁴ / (384EI). The standard structural-design check for serviceability — verifies whether a beam stays within deflection limits like L/250 or L/360 under service loads.
