TRANSVEESE STRAIN. 



Exp. VI. — Bar of Steel from the Hojmatite Steel and Iron Company. Dimen- 

 sion of bar 1-016 inch square. Length between supports 4 feet 

 6 inches. Mark on bar, " II3 + ." 



Jtesults of Exp. VI. 



Here the weight {w) at the limit of elasticity is 660 lbs., and the corre- 

 sponding deflection {h) is -882. 



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

 and section (Dj) = -001406. 



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

 = 28,000,000. 



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

 pressure = 29,080,000. 



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

 = 24-25. 



By formiUa (9). — "Work of deflection («) for unity of section = 23-49. 



By formula (12). — Value of C, the unity of working strength = 3-781 tons.
