Discussion Overview

The discussion revolves around the relationship between the shape of an object and its response to various types of vibrations, specifically harmonic and electromagnetic vibrations. Participants explore how these vibrations might influence the shape of materials, particularly those that are plastic or capable of crystallization.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant suggests that intense harmonic vibrations could cause an object to change shape to match the source, particularly if the object is plastic.
  • Another participant requests clarification on the type of object and shape being discussed, indicating the need for specificity in the inquiry.
  • A participant references a demonstration from a television program where acoustic vibrations affect a mixture of flour and water, implying that different conditions yield different results.
  • Discussion includes the potential for various shapes of materials, such as rectangular quartz crystal oscillators, to respond to vibrations, with a focus on liquids that can crystallize and metals.
  • A question is raised about whether intense electromagnetic vibrations of a single frequency could similarly affect the shape of matter.

Areas of Agreement / Disagreement

Participants express varying degrees of agreement on the general concept that vibrations can influence shape, but there is no consensus on the specifics of which materials or conditions apply. Multiple competing views remain regarding the types of vibrations and their effects.

Contextual Notes

Participants note that different conditions can lead to different outcomes, and there is ambiguity regarding the definitions of terms like "plastic" and the types of objects being discussed.

Who May Find This Useful

This discussion may be of interest to those exploring material science, acoustics, and the effects of vibrations on different states of matter.

Can intense harmonic vibrations cause an object to change shape to match the source or take that shape if it is plastic?
 
Physics news on Phys.org
Can you be a little more specific? What kind of object? What kind of shape?
 
in a general way yes...Have you seen BIG Bang theory program where the guys place flour and water in a container subject to acoustic vibrations...

but as already implied in the above post, different conditions mean different results.

I checked here just to see the definition of "plastic"...LOTS of different formulations as I suspected.

Such as a rectangular quartz crystal oscillator. Other shapes too of the same material.

By an object I mean something liquid that will also crystallize like liquid that can crystallize. I'm not sure if liquid crystal inside of lcds count. Even a metal object could be it if it were subject to the vibrations.

If this wouldn't work with harmonic vibrations would intense electromagnetic vibrations of a single frequency have this effect on matter?
