A CONTRIBUTION TO THE COMPUTATION OF THE YOUNG MODULUS

UDC 520.1+539.4

The shape of a long bending elastically deformed bar of 
arbitrary cross section and the line of motion of the moving end have 
been found by solution of the variational problem with one moving 
boundary with the use of the transversality condition. The results 
obtained allow alternative recommendations for experimental measurement 
of the Young modulus of many elastic materials.
