Question

(4) Derive equations for the following model (a simplified version of a platform suspended on top of a flatbed truck). Use Hooke's law for the springs and a linear model for damping (Fe = -dic). We assume that platforms always remain horizontal (no tilting) due to the applied forces. Hint: don't be fooled by the arrangement, the masses are connected as in the earlier homework problem, except that here we have dampers and the external force is applied to the middle mass. TTTTTTTTTTTTTTTTTTTTT
