A uniform slender rod of length L and mass m is pinned at point *O' and connected to a linear spring of stiffness k as shown in Figure la. i. Determine the relationship that defines stability of the undamped system. ii. A linear dashpot of damping coefficient c is added to the system as shown in Figure lb. Given the following parameters: L=0.4 m, b=0.1 m, m=1.5 kg, k = 50 N/m and c = 100 Ns/m, determine an expression for the response of the system if the initial angular displacement and initial angular velocity are 0 rad and 1.5 rad/s respectively. k k ww b b Figure la Figure 1b
