Deflection in a shaft | |||

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.
