Dimensional Analysis Balance

Quality control for a physics simulation starts before a single number is computed: does the equation even balance dimensionally? This simulator turns that check into a physical 3D balance scale — pick a quantity for the left pan and one or two quantities for the right pan from a library of real mechanical quantities (force, energy, pressure, momentum, and more), and watch the beam settle under a genuine damped rotational-oscillator simulation while a separate, exact verdict tells you whether the SI base-unit exponents of mass, length and time actually match. Try F = m·a (valid) versus F = m·v (invalid) to see both a physically satisfying beam motion and a hard pass/fail dimensional-homogeneity check side by side — the same discipline engineers use to catch a broken formula before it ever produces a plausible-looking but wrong result.
