Unformatted text preview: What assumptions must be made to have a simple solution? Prob 3.14 [3.18] With problem as stated on page 235 . Zero damping case. a) Solve by convolution integral for a solution before or equal to t1 and then for time greater than t1. Assume initial conditions are zero. Get the equation in terms of symbols, not actual values of parameters. b) Write a Matlab m-file to compute and plot the response versus time for the mass. Consider 4 cases and over plot the results on one figure. A legend will be required here also for clarity. Use the values of t1 equal to 0.1, 1.0, 2.0 and 4.0 seconds and plot the response from time zero to a time of 4 natural frequency periods. c) Discuss what you find. R. Gordon Kirk...
