To Calculate:The frequency of vibration.
Answer to Problem 20P
The frequency of vibration is
Explanation of Solution
Given info:
Mass of block
Spring stiffness coefficient (for both spring)
Formula used:
Here,
For equilibrium the net force is equal to zero.
Calculation:
When object is completely coincided with
When object is slightly below the x axis, then we apply the Newton's 2nd law of motion.
This looks like the general formula for the simple harmonic motion, here the effective spring constant is
Conclusion:
Thus, the frequency of vibration is
