Can you explain why Figure for 4.27 looks that way? I had a much different solution.

Thank you!

Did you have the same M? If so, for small frequency ratios it looks like 0/1 and for large it looks like 1. When the ratio is equal to one, the denominator is equal to zero, so it blows up.

For problem 4.27, could you explain why the solution makes sense for very high frequencies? I can't picture what the resulting motion would be. Why does it make sense that the magnitude of the resulting motion is r*me/m?
