Final Due June 9, 2010 Problem 1 1. Explain why the system graphically depicted in Figure 1 simulates a “dam- aged” vehicle traveling on a rough road. 2. Compute the response z ( t ) as well as the force f ( t ) transmitted to the vehicle. Would you buy such a car? Why? Problem 2 1. Using an exact method, ±nd the response of the system shown in Figure 2. 2. Using the added mass method, ±nd the response of the same system. 3. Plot the time-histories of both computed responses and compare the ob- tained results. Problem 3 Assume that d is such that the system shown in Figure 3 is lightly damped. 1. Compute a good approximation of each of its two damped frequencies. Problem 4 1. Find the eigenmodes of the discrete system shown in Figure 4. 2. Consider a free-free rod with a uniform cross section. Compute and plot the ±rst three natural modes of vibration of this rod. 3. Compare the answers to the above two questions and draw conclusions
