Abstract

Kružno ili torzijsko njihalo je tijelo učvršćeno tako da može rotirati oko jedne osi. Najvažniji dio kružnog njihala je spiralna opruga, koja skupa sa kotačem sačinjava harmonijski oscilator. Cilj rada je nadodavanje eksperimentalnom postavu kružnog njihala element koji prati i bilježi pomake kotača u vremenu te na taj način služi kao precizan mjerni uređaj za proučavanje oscilacija. Za ovu svrhu koristili smo računalnog miša. U radu su objašnjeni najvažniji dijelovi eksperimentalnog postava. Opisano je kako je računalni miš uklopljen u postav korištenjem računalnog programa. Navedena su mjerenja koja su rađena i dani su njihovi rezultati.

Abstract (english)

The torsion pendulum is a body fixed so that it can rotate about one axis. The most important part of the torsion pendulum is the coil spring, which together with the wheel forms a harmonic oscillator. The aim of this paper is to add to the experimental setup of a torsion pendulum an element that monitors and records wheel movements over time and thus serves as a precise measuring device for studying oscillations. We used a computer mouse for this purpose. The paper explains the most important parts of the experimental setup. It is described how a computer mouse was incorporated into the setup using a computer program. The measurements that have been made are listed and their results are given.
