Setup State Space Equation
Problem Statement
Find an input function such that the lower mass, , is stationary in the steady state. Find the equation of motion for the upper mass, .
The use of one spring between the masses is just a simplification of a multi-spring system, so the possibility of being off-kilter is neglected and just the vertical forces are considered.
Initial Conditions and Values
Let the initial conditions be zero for the time being.
