A stone hangs by a fine thread from the ceiling, and a
section of the same thread dangles from the bottom of
the stone (Fig. 4–36). If a person gives a sharp pull on the
dangling thread, where is the thread likely to break:
below the stone or above it? What if the person gives a
slow and steady pull? Explain your answers.
