Calculation of velocities using projections of displacement and rigid body dynamics

Cilj ovog završnog rada bio je baviti se problemima i objasniti dva velika područja klasične mehanike; kinematiku i dinamiku. Najprije su, za oba područja, definirana osnovna načela i teorijske pretpostavke, a zatim su dana rješenja zadanih problema. U prvom dijelu rada koji se bavi kinematikom, riješen je štapni sustav pomoću planova pomaka gdje su pokazani načini rješavanja problema kinematike. U drugom dijelu koji se bavi gibanjem krutog tijela, pokazane su glavne značajke dinamike počevši od određivanja težišta tijela te momenta inercije, do određivanja najveće kutne brzine tijela i konačnog broja njihaja prije zaustavljanja.The aim of this final work was to deal with problems and to explain two great branches of classical mechanics; kinematics and dynamics. First, for both parts, the basic principles and theoretical assumptions are defined and then are given solutions to the given problems. In the first part which is dealing with kinematics, the rod system was solved using displacement plans where the ways of solving kinematics problem were shown. In the second part, which deals with the motion of a rigid body, the main features of dynamics are shown, starting from determining the center of gravity of the body and moment of intertia, to determining the maximum angular velocity of the body and the final number of oscillations before stopping
