1thanks for that ,rohan ,i never thought a rod would behave like a spring,i got the answer but
won't the distances moved by spring and rod be different,the one for the rod shold be much lesser than that of the spring?
One end of a long metallic wire of length L is tied to the ceiling .the other end is tied to a massless spring K,a mass m hangs from the free end of the spring ,cross area and youngs modulus of rod are A and Y,find time period for small oscill of m.
SRC :IIT - JEE 1993
I'm having trouble writing the energy relation for the rod,please help

1you can find the equivalent spring constant
= as they are in series =
1/(
1/k+1/(AY/L))
11ya but just consider it as a simple cases of two spring in series
