 TABLE 8 PROPERTIES OF GALVANIZED STEEL WIRE'

1 From the Simplex Manual. 



The strength of steel wire varies from 50,000 pounds per sq. in. to 300,000. pounds 

 and over, depending on the kind and treatment of material. 



By using the values of breaking strain shown in the above column the breaking 

 strain figured on any other basis than 100,000 pounds per sq. in. may easily be 

 computed 1 . For example, with a wire with a breaking strain of 80,000 pounds per 

 sq. in., take eight-tenths of the tabulated breaking strain for whatever size of wire 

 the actual breaking strength is desired.
