280 P. W.Bridgman — Crystalline Cylinders. 



structure of this particular substance does not have an important 

 effect on the large scale phenomena. 



The largest extra term introduced into the strains by crystalline 

 structure is in e n , which at the inner surface reaches 34$ of 

 the maximum strain at any point of the cylinder. This is com- 

 paratively large ; one might expect that it would be instrumental 

 in leading to rupture, but the discussion of the previous paper 

 shows that this is not the case. For all the substances examined 

 rupture seemed to have no connection with any strains or stresses 

 introduced by crystalline structure. The greatest extra stress 

 introduced by crystalline structure is in dz, which at the inner 

 surface reaches ±7% of the applied stress and 23^ of the maxi- 

 mum stress at any point of the cylinder. Here again the effect 

 is large, but it seemed to have no determining effect in rupture.
