 Shaft Diameter Calculations Post Reply Forum
 Posted by: mikee122 ® 04/27/2007, 16:04:08 Author Profile eMail author Edit I am looking for either a simple formula or simplified formulas to determine the min. shaft diameter. For example I know the torque vaule, the type of loading (repeated torsion), the length of the shaft with the maximum amount of Angle of twist.T=50,000 Loading = 4 Shaft length = 20 foot Max AOT = 10 degreesI plan on using 4140 Steel, normalized (TS 148,000 psi, YS 95,000 psi)In the event there are several formulas please list in a logical order

DONT GIVE UP THE FAITH
