Here the weight (iv) at the limit of elasticity is 910 lbs., and the cor- 

 responding deflection (h) is 1-057. 



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

 and section (DJ = -0013333. 



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

 = 29,524,000. 



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

 pressm-e = 28,] 79,000. 



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

 = 40-078. 



By formula (9). — "Work of deflection («) for unity of section = 37-269. 



By formula (12). — Value of C, the unit of working strength = 4-907 tons.
