| Abstract: | In this paper, using the weighted residual method, the author obtains the approximate solutions for the torsion problems of columns with isosceles triangle and rectangular cross sections and the flow problems of the pipes which have the same sections as the columns. The approximate solutions have the desirable precision.In this paper, the author proposes the ideas " rate collocation of regions". |
