Understanding the Equivalence of Two Mechanical Systems

[QUOTE="BvU, post: 5658954, member: 499340"] Text is perfectly clear. But I concede it's a bit weird at first: after all the various elements seem to be in parallel. Perhaps it becomes clearer to you if you write the equations for a simpler case. E.g. just the two springs: ##\ f = (K_1 + K_2) x\ .\ ## And you see that ##\ Z_{\rm tot} = Z_1 + Z_2 \ ## -- that's why they call it series. Now add the mass and write the equation linking ##\ f, \ M, \ K_1, \ K_2 \ ## in a similar form. Once you get that, the ##C_1p## and ##C_2p## are a piece of cake. [/QUOTE]
