A CONTRIBUTION TO THE COMPUTATION OF THE YOUNG MODULUSS. O. Gladkov 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.
