【Abstract】 By means of the basic theory of plane problem in elastic mechanics and using half adverse solving method,the stresses and displacements of statically indeterminate beams fixed at two sides under the action of concentrated load are calculated.The results are compared with the material mechanics solutions. The precision and applicability of solutions of material mechanics are discussed from above solutions.All these may be helpful for structure design and elastic mechanics teaching.更多还原
