short ranges an empirical formula of the Gordon type could be 

 found for each range which would represent experimental results 

 much more closely. 



4. The subject of beams with endlong compression does not 

 appear to have been tested by experiment to anything like the 

 extent that the interest and importance of the subject would 

 justify. 



The strut-beams tested by the author had their lateral loads 

 concentrated at the centre, but perhaps a more interesting case still 

 would be that of a uniform lateral load such as is obtained in the 

 coupling rods of a locomotive or in a horizontal strut loaded by its 

 own weight, or in other ways. 



The above experiments were carried out in the Engineering 

 Laboratory, and the author's thanks are due to Professor Ewing 

 for providing the facilities for the investigation.
