| Abstract |
The WKB method is used to construct an approximate analytic solution of the equation of small nonstationary vibrations of the Meshcherskii mathematical pendulum. The versions of linear and nonlinear variation in the pendulum mass are considered. Calculations showed that, under certain restrictions on the pendulum parameters, the approximate solutions constructed in elementary functions are a good approximation to the exact results. |
