PASSAGE
A mechanical engineer is designing a door-closing mechanism modeled as a rotational spring-mass-damper. The specification requires that the door return to the closed position as quickly as possible without overshooting (i.e., without the door bouncing back open). The engineer has freedom to choose the damping coefficient c.
Which damping condition satisfies the design specification, and what is the physical consequence of choosing a damping coefficient that is even slightly below this target value?
