Let us consider the problem of forced symmetrical oscillations of a thin hemisphere of radius R with a mass of M, rigidly fixed along the equator, under the influence of a normal load of constant surface density R. The front of the load wave propagates at a constant velocity ѵ...

The problem of calculating the natural frequencies of axisymmetric oscillations of a thin hemisphere of radius R with mass M, rigidly fixed at the equator is considered.
