摘要：
Natural vibrations of a rectangular plate with two clamped and two freely supported edges are under consideration. The Bubnov - Galerkin method is used to calculate the first eigenvalues, and the first eigenvalue in the case of a single trial function is calculated with an error smaller than 1%. The results are compared with known data, and eigenforms are given.
