PPT-11-5 Damped Harmonic Motion

Typically harmonic motion decreases in amplitude with timethis realistic model describes damped harmonic motion The damping effect is a result of friction and internal resistance of the system to further motion. Lecture 22 Phase and Phasor representation Objectives In this lecture you will learn the following Phase between excitation and response Phasor analysis of resonance behaviour So far we focussed our attention on the amplitude of vibration and let u The simplest harmonic resonances can be found in highly constrained dynamicsystems, like a pendulum that is free to swing only within a plane, or a linearmass-and-spring system sliding back and forth Resistively Damped Operation2Copyright Main results of the tuner study by 3D modeling. 1/5/2017. 2-nd harmonic cavity meeting. 1. 2D analysis results refresher. 1/5/2017. 2-nd harmonic cavity meeting. 2.

For a simple harmonic oscillator, apply the relationship between position . x . Describe . examples of damped oscillations.. . Need to know. - It is sufficient for students to know that damping involves a force that is always in the opposite direction to the direction of motion of the oscillating particle and that the force is a dissipative force.. Explain how force, velocity, and acceleration change as an object vibrates with simple harmonic motion.. Calculate the spring force using Hooke’s law.. OBJECTIVES. What is periodic motion?. A repeated motion (e.g. pendulum swinging) that is back and forth over the same path.. Science of Sound, . Chapter 17. Resonance in Singing, . Miller. Acoustics for Choir and Orchestra , .
