Abstract

U radu je dan opis kinematike gibanja materijalne točke pri čemu je istaknuto gibanje materijalne točke po kružnici. Definirane su jednadžbe gibanja pri rotaciji krutog tijela te princip rada i kinetičke energije. Analiza kružnog gibanja provedena je na primjeru apsolutno krutog štapa koji je zglobno oslonjen u polovini raspona. Primjenom mehaničkih zakona proveden je dinamički proračun te su izračunate reakcije u osloncu tijekom gibanja. Određene vrijednosti uspoređene su s primjerom stvarnog... More fizikalnog modela klackalice za koji je pomoću programa za video analizu određene vrijednosti kinematičkih veličina tijekom gibanja te su izračunate vrijednosti reakcija u osloncu. Less

Abstract (english)

The bachelor thesis describes the kinematics of the particle motion, emphasizing the motion along a circle. The equations of motion for the rotation of a rigid body are defined, as well as the principle of work and kinetic energy. The analysis of circular motion was carried out on the example of an absolutely rigid beam supported in the middle of the span. The values of kinematic variables and support reactions are determined by applying previously described mechanical laws. Certain values... More have been compared with the values obtained for real physical model of a seesaw for which kinematic magnitudes during motion have been determined by a video analysis program and the values of the reactions in the support have been calculated.
