| Abstract: | By means of the basic theory of plane problem in elastic mechanics anct by using naif adverse solving method, the stresses and displacements of beams with one degree of indeterminacy under the action of concentrated load are calculated, and the results are compared with the material mechanics solutions. The precision and applicability of solutions of material mechanics are discussed from above solutions. The results may be helpful for structure design and elastic mechanics teaching. |
