摘要：The paper examines the application of the tensor calculus to the classic problem of the pure torsion of prismatic rods.The introduction contains a short description of the reference frames,base vectors,contravariant and covariant vector coordinates when applying the Einstein summation convention.Torsion formulas were derived according to Coulomb’s and Saint-Venant’s theories,while,as a link between the theories,so-called Navier’s error was discussed.Groups of the elasticity theory equations were used.
