Calculation of velocities using projections of displacements and rigid body dynamics

This final work contains two branches of mechanics - kinematics and dynamics. The main task of the final work is to solve the default tasks in the field of kinematics and dynamics. In the first part of kinematics, the basic rigid kinematics theorem, the planar motion, the current center of the shift, the velocity and the pojections of velocity are explained. The task involved solving the rod system using a velocity projections (graphical and analytical method). The second part of the final work deals with the dynamics and the terms that are explained are: the moment of inertia and the law of conservation mechanical energy. The task of this study was to study the body movement or swinging. It was necessary to determine the reactions in support B at the shown moment and at the moment when the highest angular velocity was postponed as well as the ordinal number of the swings under which the body would stop. In the first assignment, which deals with kinematics, the basic theorem of rigid body kinematics, the planar body motion, Kennedy's theorem, and the plan of horizontal and vertical shifts were explained. The task involves the solution of the rod system by means of a shift plan. Second assignment involves the general motion of the rigid body, the law of conservation mechanical energy, the types of dynamic and kinematic motion. An example of this task was the motion of the rigid body.
