## Main Question or Discussion Point

hello all,

Recently I have been attempting to model a spring system (see below) where the springs themselves will hold mass. I should know how to do this but i accept defeat, how do you model the potential energy or a force system on two masses connected to three springs? I have read about effective mass but i fail to fully understand. Thank you all for the celerity.

In this design the spring system is vertical and grounded on both ends. Many thanks!
