A static model to determine the critical wind speed for overturn-, sideslip- and rotation-type of accidents is considered. The basic equations were defined by assuming that the vehicle moves in a uniform straight line. Explicit formulas for the critical wind speed for all three possible wind-induced accidents are derived to provide the new critical wind speed formulas for rollover and rotation wind-induced accidents. Numerical examples are given and compared to field observations.

Two ways of calculating the mutual restitution coefficient are given: one based on car masses and one based on car stiffness. A numerical example of an actual test is provided.

It is shown that the presence of the channel results in the splitting of the otherwise degenerate ground state. When the width of the channel is small compared to the wavelength of the particle, the wavefunction in the channel is exponentially

It is shown that the authors fail to correctly determine the domain of the tip angle and consequently they obtain some incorrect solutions.

The governing equations are presented and two cases allowing for a steady-state solution are considered: rolling on consistently rough ground and rolling on perfectly smooth ground. The conditions of steady motion are derived for both kinds of ground and it is shown that the possible steady motion of a disk is either on a straight line or in a circle. Oscillations about steady state are discussed and conditions for stable motion established. The bifurcations of steady motions on a smooth surface are also considered.

The derived equations include a parameter which allows the interpretation of the theories as an approximation of isotropic plates or transversally inextensible plates. Qualitative comportment between the theories is also given.
