Frequency and viscous friction in a spring?

Click For Summary

Discussion Overview

The discussion centers on the relationship between frequency and viscous friction in the context of a spring, particularly in damped oscillatory systems. Participants explore the implications of viscous friction on the behavior of springs and oscillators.

Discussion Character

  • Technical explanation, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant inquires about the formula relating frequency and viscous friction in a spring.
  • Another participant references Hooke's Law and the angular frequency formula, suggesting a basic understanding of spring mechanics.
  • A subsequent reply indicates that while the initial equation is correct, it does not account for viscous friction, prompting a search for a modified relationship.
  • Another participant explains that in a damped oscillator, resistance is modeled as proportional to velocity, asserting that frequency is not directly influenced by the friction force, but rather affects the power delivered to the system.
  • This participant suggests that knowing the spring constant and frequency allows for the determination of velocity as a function of position by solving the corresponding ordinary differential equation (ODE).

Areas of Agreement / Disagreement

Participants do not reach a consensus on the relationship between frequency and viscous friction, with multiple viewpoints and interpretations presented regarding the effects of damping on oscillatory motion.

Contextual Notes

The discussion does not resolve the mathematical steps necessary to derive a comprehensive relationship between frequency and viscous friction, nor does it clarify the assumptions underlying the models referenced.

Hi.
may i ask the relationship(formula) between frequency and viscous friction in a spring?
 
Physics news on Phys.org
are you talking about hookes law F=-Kx
And the angular frequency would be w=square root of k/m
 
your equation is right if not consider the viscous friction, but since it must consider the friction, so how arh?
 
In a damped oscillator the resistance is just modeled as proportional to velocity. The frequency has nothing to do with the friction force, it will just increase power delivered to the liquid.

If you know spring constant and frequency, then you can find v(x) by solving the ODE. I guess that's what you're asking.
