The speed of the second hand in a clock is higher than that of the minute hand and the hour hand, so the rotation is most easily affected by external forces. And hanging clock, scale from 12 to scale, 6 second hand's own quality of second hand axis formed at the same moment and the driving moment of the clock itself, can help the second hand, when the second hand scale from 6 position began to scale, 12 second hand drive moment and the moment produced by its own clock walks on the contrary, the moment of maximum when the second hand in the dial 9 position, beyond that point, torque and reduced. So when the clock runs out of energy, the moment that drives the second hand becomes weaker and weaker, unable to resist the reverse moment of the second hand's journey from the sixth to the ninth, the second hand often stops at this point, especially near the nine point of maximum reverse torque.
