Sometimes a car develops a pronounced rattle or vibration at a particular speed, especially if the road is hot enough that the tar between concrete slabs bumps up at regularly spaced intervals. Reread Sections $11-5$ and $11-6,$ and decide whether each of the following is a factor and, if so$,$ how: underdamping, overdamping, critical damping, and forced resonance.
