no no, I'm not attempt to solve anything in these question, since i don't know where to ask, so, i ask here ;P,
i just want to know mechanism on a normal grandfather clock pendulum which is normally convert one second until one complete oscillation, or only half oscillation.

sorry, if my grammar so terrible

No, its was well put, i didn't read it correctly.

I http://electronics.howstuffworks.com/gadgets/clocks-watches/clock.htm/printable" it depends on the size of the clock.
Small Cuckoo clocks have 4 theta per second,
Medium wall clocks 2 theta per second,
Large Grandfather clocks 1 theta per second.

You can hear it in their ticking actually, maybe if you youtube it you'll get a more solid answer.
