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).

Concrete Mix Design Calculator

Estimate the total cement mass needed for a concrete batch based on target strength, volume, exposure conditions, and aggregate size. Use it when planning material quantities for slabs, columns, or footings.
