Strain of a wire tied with an angle in a beam

Click For Summary

Discussion Overview

The discussion revolves around determining the strain of a wire attached to a cantilever beam that is subjected to vibrations. The wire is pulling the beam at an angle, and the participant seeks a method to relate the strain in the wire to the displacement data obtained from the beam's vibrations.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant describes a cantilever beam with displacement data from vibrations and asks if there is a way to calculate the strain of a wire attached at an angle.
  • Another participant questions whether the inquiry is related to schoolwork, suggesting it may belong in a different forum.
  • A third participant suggests addressing a related problem from another thread before returning to this topic.
  • The original poster clarifies that the inquiry is part of a personal project and discusses the challenges faced with the wire's force requirements when not angled.
  • The original poster mentions using a specific material that varies its force based on strain and expresses a need for accurate methods while conducting simulations.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the method to calculate strain, and multiple perspectives on the nature of the inquiry (project vs. homework) are presented.

Contextual Notes

The discussion includes assumptions about the relationship between beam displacement and wire strain, but these assumptions are not fully explored or resolved. The specific material properties and their effects on force and strain are also not detailed.

Well, i have a cantilever beam where i have the displacement of the tip of the beam (y axis) data from a vibration of this beam. In the tip of the beam is a steel wire attached, pulling up the beam with an angle (30º for example).

I want to know if exists a form to obtain the strain of the wire based on the displacement of the beam (the vibration).

Thanks

Are these beam questions of yours for schoolwork? If so, they should be posted in the Homework Help forums...

@Gerrgegeorge :

Let us deal with the basic problem on your other thread first . We can come back to this one later .

No, is a project of mine.

I am using a specific material to control the vibration of the beam, this material is a wire. I have tried without the angle (paralel to the beam) but in this mode the force that i need is much high.
As my material varies is force based on his strain i need this information, but the problem is that i only have the vibration of the beam information (strain gage)

I have some ideas, but as i making simulations i want to know the right method.
