Hey, I'm looking to find how much twist I have in a long drive shaft. The shaft is driven over 15 ft from one end, and I want to select a suitable drive shaft which will have minimum twist. Does anyone know the calculations I would need?

Thanks

-James

According to the "Machinery's Handbood" the formula for Torsional Deflection of circular shafts is...

For a solid circular shaft the torsional deflection in degrees is given by:

< = (584Tl)/(D^4G)

< = angular deflection in degrees

D = diameter of shaft in inches

G = torsional modulus of elasticity = 11,500,000 lbs/square inch for steel

T = torsional or twisting moment in inch-pounds

l = length of shaft in inches

Hope this helps.
