Calculation of speeds using motion plans and dynamics

The 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. The first part 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 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. An example of this task was the motion of the rigid body movement or swinging. In the following problem it was necessary to determine the reaction in example A in the given moment, and when it reaches its maximum angular velocity. Additionally, it was necessary to approximately determine the number of swings before the subject stops. The review was executed using Microsfot Excel.
