The force equilibrium equations can thus be expressed as Fs = Fs1 Fs2 Fs3 Fs4 Fd = Fd1 Fd2 Fd3 Fd4 where Fs Fd = W with W denoting the total vertical force including the inertia force acting on the milling machine From Fig d we have Fs = keq x # Fd = ceqx Equation along with Eqs and yields keq = k1 k2 k3 k4 = 4k ceq = c1 c2
