ABSTRACT
Summing vectorially, the net horizontal force is
Observe that the net horizontal force is not a func tion of the object’s rotation speed - the terms multiply ing ω are identically zero [5]. Furthermore, the second term in this equation is a constant linear damping term. Substituting N from Equation 1 yields
The 2 x 2 spring constant matrix ks, and the offset force vector f Q are constant while the object rests on a particular set of supports.
