TASMANIAN I'lMUKKS. 



TASMANIAN -AUSTRALIAN TIMBERS. 



(A. O. Green.) 



Approximate Breaking Weights for Stresses, of Crushing, 

 Shearing, and Tension, in pounds per square inch, from 

 experiments of Professor Kernot, Melbourne University »^ 



EUROPEAN TIMBERS. 



* Note. — For Australian timbers, and given as an approxi- 

 mate guide, for the breaking weights of Tasmanian timbers, 

 data for which are wanting. The weights given for European 

 timbers are from results obtained by the experimenters 

 enumerated at the head of the Table of Weights and Transverse 

 Strengths on page 29. 



For purposes of comparison, the " Shearing across the grain " 

 shown for the Tasmanian woods may be taken as equivalent to- 

 the " Tension across the grain " shown for European.
