The results tabulated in Table 3 shows that T will increase when we add more mass higher I. Although there are one amplitude 40o which had a result of 0. Radius of disc Discussion of Results 4.
The wire length was measured with a simple steel ruler, with increment of 1mm. When damped, the amplitude of oscillation deteriorated rapidly over time, causing the disc stopped after just a few oscillation. This relationship is constant, because it is a straight line graph.
When released, the torsion moment of the wire will attempt to untwist itself, causing the disc to oscillate back and forth around the wire axis, creating a harmonic motion.
However, an observation was made. As mentioned earlier in section 4. Mechanical properties of metals. The initial mass was calculated to be 2. The square of period of oscillation T2 were calculated from the average reading squared.
This suggest that T is not dependent of the initial amplitude. The measurement equipment used are namely the angular scale on the disc read off a pointera steel ruler measuring to 1mm,a digital vernier caliper measuring to 0.
Processing of Data The first measurements taken were the dimensions of the Torsional Pendulum. If we take it that T has no error, therefore the gradient of T2 vs Mn can be assumed correct. Get Full Essay Get access to this section to get all help you need with your essay and educational issues.
Objectives To investigate the harmonic motion of a torsional pendulum upon angular deflection. Damping is a way of reducing the energy of the oscillation by dissipating some energy through friction.
Having seen from the error analysis from section 4.
A digital stopwatch was used for time measurement, recording up to 0. A total of six various Mn will be used, and their measurements taken twice and averaged. To further reduce the amount of human reaction related problem, the Torsional Pendulum setup can be modified or redesign to incorporate a better system for counting and timing the oscillation.The Pit And The Pendulum Essay Examples.
