How Do You Calculate Oscillation Frequency for a Mass with Two Springs?

Click For Summary
SUMMARY

The discussion focuses on calculating the oscillation frequency of an 8.3 kg mass attached to two springs with spring constants of 28 N/m and 62 N/m. The correct approach involves determining the effective spring constant of the system, which is not simply the difference between the two constants. The frequency of oscillation is calculated using the formula \( f = \frac{1}{2\pi} \sqrt{\frac{k_{\text{eff}}}{m}} \), where \( k_{\text{eff}} \) is the effective spring constant. The correct frequency of oscillation is approximately 0.322 Hz.

PREREQUISITES
  • Understanding of Hooke's Law and spring constants
  • Familiarity with the formula for oscillation frequency
  • Basic physics concepts of mass and force
  • Knowledge of equilibrium conditions in spring systems
NEXT STEPS
  • Research how to calculate effective spring constants in series and parallel configurations
  • Learn about the principles of harmonic motion and oscillation
  • Explore the impact of damping on oscillation frequency
  • Investigate real-world applications of oscillation frequency in mechanical systems
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and oscillatory motion, as well as educators looking for practical examples of spring systems in action.

Homework Statement



A 8.3 kg mass slides on a frictionless surface
and is attached to two springs with spring
constants 28 N/m and 62 N/m that are on either side of the mass.


Find the frequency of oscillation. Answer
in units of Hz.

Homework Equations



(2pi sqrt(m/k))^-1

The Attempt at a Solution


subtract the constants from each other to find the coonstant of the system. use this in the equation above. I got about .322Hz is this right?

You need to rethink the combined effect of the two springs. At equilibrium, each spring is pulling the mass with the same amount of force. What happens to each of those forces when the mass is moved to one side?
