Does Mass Affect Vibration Response in Single Degree of Freedom Systems?

AI Thread Summary
In a single degree of freedom system, a larger time period (T) correlates with greater peak deformation due to the system's mass and stiffness relationship, expressed as T=2*pi*sqrt(m/k). While increased mass results in a longer time period, which typically leads to higher peak deformation, it also introduces greater inertia. This greater inertia could suggest reduced peak deformation; however, the dominant factor remains the time period's effect on deformation. The discussion highlights the complexity of these interactions and the need for clarity on how mass and inertia influence system behavior. Understanding these dynamics is crucial for accurately predicting vibration responses.

Considering the free vibration response of a single degree of freedom system:

It is observed ,that, larger the Time Period (Vibration Period -"T") of the system(consider a single degree of freedom system), greater is the peak deformation of the system.Right?

Time Period on the other hand is directly proportional to the mass (m)(T=2*pi*sqrt(m/k)) , k being the stffness of the system.

This means a system having more mass hence more "T" will have higher peak deformation.Right?

But if a system has more mass it offers more inertia, right?Now, if the system offers more inertia should'nt the peak deformation be less??

Plz. help!

Why do you say that?

Thread 'Is there a white hole inside every black hole?'

This is what I am thinking. How much feasible is it? There is a white hole inside every black hole The white hole spits mass/energy out continuously The mass/energy that is spit out of a white hole drops back into it eventually. This is because of extreme space time curvature around the white hole Ironically this extreme space time curvature of the space around a white hole is caused by the huge mass/energy packed in the white hole Because of continuously spitting mass/energy which keeps...
