Calculation of velocities using displacement plans and body dynamics

Ovim su završnim radom teorijski obrađene dvije grane mehanike – kinematika i dinamika, te su provedeni proračuni dva zadatka koji obuhvaćaju primjenu planova pomaka i principe gibanja složenog krutog tijela. Kroz teorijsku razradu kinematike – grane mehanike koja proučava gibanje tijela isključivo u geometrijskom smislu te ne sagledava uzroke gibanja, mase tijela te djelovanja na konstrukcije, obrađeno je devet poglavlja koja daju uvid u teorijski pristup rješavanja kinematičkih problema te pobliže opisuju kinematičke teoreme i principe. Na kraju prve polovice završnog rada riješen je zadatak uz upotrebu planova pomaka. U drugoj polovici rada teorijski je obrađena dinamika – grana mehanike koja proučava gibanja tijela pod djelovanjem sila koje uzrokuju to gibanje. Zakoni dinamike pojašnjeni su kroz tri poglavlja. Na kraju druge polovice rada riješen je zadatak uz upotrebu principa gibanja složenog krutog tijela.This final paper theoretically deals with two branches of mechanics - kinematics and dynamics, and shows calculations of two problems that include the application of displacement plans and the principle of motion of a complex rigid body. Through the theoretical elaboration of kinematics - a branch of mechanics that studies the motion of bodies exclusively in geometric terms and does not consider the causes of motion, body mass and action on structures, nine chapters are presented that provide insight into the theoretical approach to solving kinematic problems and describe kinematic theorems and principles. At the end of the first half of the final work, a problem was solved with the use of displacement plans. The second half of the paper theoretically deals with dynamics - a branch of mechanics that studies the motions of a body under the action of the forces that cause that motion. The laws of dynamics are explained through three chapters. At the end of the second half of the paper, a problem was solved using the principle of motion of a complex rigid body
