I have seen he contents and i think its very useful things
and I am very much interested to go through the
details..

hrishi wrote 13 years ago.
wanna learn

nice

Benjamin wrote 13 years ago.
I need solution to this problem.
A mass M1 is suspended from a fixed point by means of
spring of stiffness K1, attached to M1 by means of second
spring of stiffness K2 with another mass M2. When the system
is set in free vibration, if the inertia of the spring is
negligible, show that M1M2W^4-(M1K2+M2(K1+K2))W^2 +K1K2 =0

just i want know about viscoelastic dampers

tanzil wrote 14 years ago.
i want the answer for this question

Determine the natural frequency of the free longitudinal
vibrations of a countilever
of length ‘C’ by equilibrium method and
Rayleigh’s method?
