The actual scientific and practical problem of plane deformation of an elastic cylinder under conditions of temperature and humidity is considered. Various pipes, shafts, plain bearings, bushings from natural and modified wood, etc. have a cylindrical shape. An exact analytical solution of this problem is given for an isotropic cylinder in the case of stationary temperature and humidity exposure. All formulas for stresses and strains and stresses contain mechanical and thermophysical constants, which corresponds to the physical meaning. It is proved that the use of classical methods for solving this problem through the potentials of stresses and displacements leads to an undesirable result in which stresses or deformations do not depend on the thermophysical constant C_2, which contradicts the physical meaning.
