S-Ha+ionary Shaft-Gradually Applied Loads 

 Bending Momenf, in 1,000 ln.-Lb 



Scales (for rotating shafts) : 



A. Gradually applied loads 



B. Suddenly applied loads, minor shocks 



C. Suddenly apphed loads, heavy shocks 



D. Severe operating conditions — high reliabihty 

 Other Values of Ss. — In making the chart on this and 



the preceding page, the value of Ss was taken as 6,000 lb. 

 per sq. in. For any other value of Ss, multiply the shaft 

 diameter by a factor from the following table.
