REPORT 1867. 



TEANSYEESE STEAIN. 



Exp. XLIII.— Bar of Steel from Messrs. Turton & Sons, Sheffield. Dimension 

 of bar 1-012 inch square. Length between supports 4 feet 6 inches. 

 Mark on bar, " H." 



Results of Exp. XLIII. 



Here the weight {w) at the limit of elasticity is 960 lbs., and the corre- 

 sponding deflection 1-270. 



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

 and section (DJ = -001382. 



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

 = 28,484,000. 



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

 pressure = 27,542,000. 



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

 = 50-800. 



By formula (9). — "Work of deflection {u) for unity of section = 49-602. 



By formula (12). — Yaluc of C, the unit of working strength = 5-570 tons.
