REPORT 1867, 



TRANSVERSE STRAIX. 



Exp. XLVII.— Bar of Steel from the Titanic Steel Co., Worcester. Dimen- 

 sion of bar -99 inch square. Length between supports 4 feet 6 inches. 

 Mark on bar, " B X." 



BesuUs ofEx'p. XLVII. 



Here the weight (w) at the limit of elasticity is 1010 lbs., and the cor- 

 responding deflection {I) is 1-232. 



By formula (6). — The mean value of the deflection for uuitv of pressure 

 and section (DJ = -001177. 



By formula (7). — The mean value of the modulus of elasticity (E) 

 = 33,446,000. 



By formula (2). — The modulus of elasticity (E) corresponding to 112 lbs. 

 pressure = 34,935,000. 



By formula (8). — Work of deflection (U) up to the limit of elasticity 

 = 51-846. 



By formula (9).— Work of deflection {ii) for unity of section = 52-892. 



By formula (12). — Value of C, the unit of working strength = 6-621 tons.
