Under the Hood

Real engineering formulas

Voltage Drop
Vd = (2 × L × I × 0.0175) / A
drop% = (Vd / V) × 100
ArtNet Addressing
net = floor(u / 256)
subnet = floor((u % 256) / 16)
universe = u % 16
CCT (McCamy)
n = (x − 0.3320) / (0.1858 − y)
CCT = 449n³ + 3525n² + 6823n + 5520
Beam Reactions
RA = W × (1 − pos)
RB = W × pos
