Calculation of velocities using projections of displacements and rigid body dynamics

U ovom radu je predstavljena podijeljenost mehanike s osnovnim izrazima i definicijama. Predstavit ćemo dvije cjeline mehanike, a to su kinematika i dinamika. Smisao završnog rada je objasniti osnovne pretpostavke i pokazati primjenu iz svakog dijela. prvi zadatak obuhvaća kinematiku, te za zadani mehanizam treba odrediti kutne brzine tijela pomoću plana pomaka, zatim rješenje kontrolirati vektorski. U drugom dijelu proračunavamo dinamiku - gibanje kutnog tijela, te za zadani primjer pokazati glavna obilježja dinamike. Zadatak se bavi određivanjem najveće kutne brzine tijela, te određivanjem broja njihaja prije nego se tijelo približno zaustavi.This paper presents the division of mechanics with basic and definitions. We will present two branches of mechanics, namely kinematics and dynamics. The goal of the final paper is to explain the basic assumptions and show the application of each part. The first task includes kinematics, and for the given mechanism, the angular velocities of the body should be determined using the displacement plan, then the solution silution should be vector controlled . In the second part, we stidy dynamics - the motion of a rigid body, and show the main features of the dynamics for the given example. The task deals with determining the maximum angular velocity of the body, and determining the number of oscillations before the body comes to an approximate stop
