On the torsion of rhombic and triangular prisms

Abstract

In the problem of torsion of prisms and in corresponding hydrodynamic problems, it is necessary to solve an indefinite equation, where K is a constant, provided that f = o along the contour of the prism. K M. Paschoud considered the case of regular polygons. Based on the proposed approach, let us consider the cases of a rhombus and an isosceles triangle.
