Dear All,

I started studying vibration recently and getting confused as I go

deep n deep into it.

A multidegree system has n natural frequencies and hence n natural

shapes.

My confusion is

Which frequency (and hence the corressponding mode shape)will the

system adopt?

Or the system will act democratically and give chance to each of its

frequency to execute one by one and one after the other. :)

In other words what is the criteria for the system to execute certain

mode shape and frequency?

Also if a multidegree system is disturbed from its equillibrium

position , will it execute all the frequencies and mode shape before

coming to equillibrium once again?

(I referred the text book .They discuss about the general equation in

terms of 'n' and conclude that the system will have n number of

corressponding frequencies.)

Regards,

Yogesh Joshi
