Problema e solução em inglês, como no livro original.
Envision holding the end of a ruler with one hand and deforming it with the other. When you let go, you can see the oscillations of the ruler. In what way could you modify this simple experiment to increase the rigidity of the system?
Responda com suas palavras antes de olhar.
You could hold the ruler at its midpoint so that the part of the ruler that oscillates is half as long as in the original experiment.
