Frequency and viscous friction in a spring?

Click For Summary
SUMMARY

The relationship between frequency and viscous friction in a spring system is primarily addressed through the principles of Hooke's Law and the dynamics of damped oscillators. The angular frequency (ω) is defined as ω = √(k/m), where k is the spring constant and m is the mass. In a damped oscillator, viscous friction is modeled as proportional to velocity, affecting the system's energy dissipation rather than the frequency itself. Therefore, while frequency remains independent of the friction force, it influences the power delivered to the liquid in the system.

PREREQUISITES
  • Understanding of Hooke's Law and its application in spring mechanics.
  • Familiarity with the concept of angular frequency and its formula (ω = √(k/m)).
  • Knowledge of damped oscillators and their behavior under viscous friction.
  • Basic differential equations for solving motion equations in mechanical systems.
NEXT STEPS
  • Study the mathematical modeling of damped oscillators in mechanical systems.
  • Learn about the effects of viscous friction on energy dissipation in oscillatory motion.
  • Explore advanced topics in differential equations related to oscillatory systems.
  • Investigate the practical applications of spring dynamics in engineering and physics.
USEFUL FOR

Students and professionals in physics, mechanical engineering, and applied mathematics who are interested in the dynamics of oscillatory systems and the effects of friction on frequency and energy transfer.

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.
