Figure 9.1: Two pendulum system for Problem 1. For the 2-DOF pendulum system (Fig. 9.1) of Problem 1 with k=500N/m,l=0.5m, and m1=m2=10kg.a is 0.1m along the pendulum. Obtain, plot (040s), and comment on the response expressions 1(t) and 2(t) for the following initial conditions: i. 1(0)=0.1rad,2(0)=0.1rad,1(0)=2(0)=0rad/s ii. 1(0)=0.1rad,2(0)=0.1rad,1(0)=2(0)=0rad/s iii. 1(0)=0.1rad,2(0)=0rad,1(0)=2(0)=0rad/s
