Strike on one side and strike on the other side.
The function of the clock hammer is as an energy storage device, so the clock can run for a relatively long time without being guarded. When winding up the clockwork driven by the hammer, the hammer can be lifted by pulling the rope. This will give the bell hammer potential energy under the action of the earth’s gravitational field. It can be seen for a while that the clock uses the potential energy to drive the mechanism when the hammer falls.
To use the falling hammer to design a simple clock-a clock with only a second hand, I want to install a second hand on this simple clock so that the normal second hand on any clock works like a normal second hand, rotating once every 60 seconds, in this simple mechanism In the middle, releasing the bell hammer will cause a rapid fall, causing the drum to rotate at a speed of about 1000 rpm (revolutions per minute) until the bell hammer falls to the floor.
