📐 Formula Reference
V = L × W × HLength, width, height in meters → volume in m³.
V = I × RVoltage = current × resistance.
ΔL = α × L × ΔTα = coefficient of linear expansion.
σ = M × y / IM = moment, y = distance from NA, I = moment of inertia.
Q = A × vArea × velocity → volumetric flow rate.
P = F × vForce × velocity → watts.
