The load was raised for 48 

 hours then lowered to distribute 

 the loading equally in all sec- 

 tions of the cable. 



This resulted in an additional 

 elongation of 7.0". When com- 

 pared to the stretch in 120 

 hours with the same load, the 

 effects of sheave resistance are 

 striking.
