Spring Force Calculator

Calculate the restoring force a spring exerts when compressed or stretched using Hooke's Law. Use it for spring selection, mechanism design, physics problems, and any application involving elastic force.

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.
