Presidential Address by Sir Alexander Gibb, G.B.E., C.B., F.R.S., on 

 Research in engineering (ii.o). 



Mr. E. H. Bateman. — The analysis of elastic structure by the methods of 

 deformatioTi-energy and remainder distribution (12.0). 



Systems of analysis referred to by various writers as the methods of 

 Virtual Velocities, Stationary Potential and Least Work are known as being 

 well suited for the solution of problems in rigid mechanics, and correspond- 

 ing methods based on Maxwell's Reciprocal Theorem have been developed 

 for application to Elastic Structures. These methods, often described 

 generically as strain energy methods of analysis, have hitherto been applied 

 in terms of forces or stresses, while little attention has been given to the 

 alternative application in terms of deformations, which the author has 

 proposed to designate the method of Deformation-Energy. 



This method is applicable to structures which are statically determinate 

 or statically indeterminate ; in cases of the latter class it may lead to simpler 

 forms of analysis than other methods, because the number of indeterminate 

 deformations may be less than the number of indeterminate forces or 

 stresses, and also because it may be easier to specify the possible deforma- 

 tions of a structure than to ascertain a convenient system of independent 

 indeterminate forces. 



The paper includes a short account of the author's method of Remainder- 

 Distribution for solving the simultaneous equations which result from the 

 application of strain energy methods of analysis to a statically indeterminate 

 structure. The method is illustrated by a solution of the problem of a 

 continuous girder on elastic supports.

Discussion on The training of university graduates for the engineering 

 industry (lo.o). 



Prof. F. G. Baily. — Introduction. 



Mr. A. P. M. Fleming and Dr. W. Jackson. 



The authors stress the need for a more effective co-ordination of the 

 resources of the Universities and of industry than is at present the case. 

 The engineering departments of the Universities should not be required to 

 provide instruction in workshop practice, machine design, industrial 

 administration and in specialised technological subjects, but should con- 

 centrate on teaching a sound knowledge of the properties of engineering
