PR01: Three-Dimensional Study the Tennis Ball Flight Read More »
ABSTRACT: In the article, mechano-mathematical modeling of the flight of a tennis ball is made, taking into account the Magnus effect. The differential equations describing the movement of the ball during lifted shots are derived depending on the initial conditions: the initial angle of the racket surface, the initial linear velocity of the swing, and
ABSTRACT: The investigations of structural constructions, which are put under dynamical excitations, by using dynamical matrices are done for models, which have many degrees of freedom. But the most real structural constructions have hysteretic damping, which is modeled as viscous damping. This fact makes the investigations more difficult. It is necessary to be used more

ABSTRACT: The investigations of structural constructions, which are put under dynamical excitations, by using dynamical coefficients are possible only for mechanical systems with one degree of freedom. That is why, to a certain extent, using of this method is limited. The most real structural constructions have many degrees of freedom. The dynamical coefficients are modified
