Unformatted text preview: MATLAB, plot the response for 1 period of the undamped natural frequency Over plot the solution for the case of zero damping. Problem 1.81 [1.92] Use the general nomenclature of L for the length of the massive uniform bar, with mass Mb and inertia about the cg of Icg Point mass of m at end of bar as in example problem. Springs of k attached at distance of l ( ie., small L ). One to either side as in example. a) Derive the equations of motion and identify equivalent rotational inertia and equivalent rotational stiffness. b) Find general expression for stable condition. c) For the springs at half point of bar as in stated problem, find the expression for stability That's all.
