Dynamic Analysis - What will be the amplitude

Click For Summary

Homework Help Overview

The discussion revolves around dynamic analysis, specifically focusing on the amplitude of a system subjected to a harmonic disturbing force of 9N. Participants are exploring the implications of this force in the context of oscillations.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • One participant assumes that the disturbing force can be expressed as 9*sin(ωt), questioning the relationship between the force and the given frequencies. Others are discussing the implications of this assumption and how it relates to undamped oscillations.

Discussion Status

Participants are actively engaging with the problem, with some providing links to external resources that may clarify the situation. There is an exploration of different interpretations regarding the amplitude and its dependence on the harmonic excitation.

Contextual Notes

There is a mention of undamped oscillations and harmonic excitation, indicating that the discussion is framed within specific parameters of dynamic analysis. However, the exact definitions and implications of these terms are being questioned and explored.

A disturbing force of 9N acts harmonically

I assume this means that the force is given with 9*sin(ωt), where ω is one of the given frequencies?
