Helpful Formulas & Rules For Calculating Springs
Spring Length = Number of coils x wire size. Example: 100 coils x .250 wire = 25"
Determine ID = Subtract the wire size twice from the OD of a spring. Example: 2 1/2" OD spring with .250 wire) 2 1/2" - .250 - .250 = 2" ID
Torsion:
Amount of Spring Growth = Number of turns x wire size. Example: 10 turns x .250 wire = 2 1/2" of spring growth
Wire Size = Inches divided by the number of coils. Example: 2 1/2" per 10 coils, 2 1/2" divided by 10 = .250 wire
Door Weight = Total IPPT of a door's springs divided by the cable drums multiplier
CAUTION: SPRINGS OPERATE UNDER EXTREME TENSION & CAN CAUSE BODILY HARM.
