Results of Exp. XXXVI. 



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

 sponding deflection {?■) is 1-160. 



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

 and section (D^) = -0013033. 



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

 -= 30,204,000. 



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

 prcssiu-e = 30,895,000. 



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

 = 46-400. 



By formula (9). — Work of deflection (») for unity of section = 45-369. 



By formula (12), — Value of C, the unit of working strength = 5-392 tons.
