principle of working of a clock????

Answer 1

A mechanical clock is principally a gear train of 5 main gears, known as wheels to horologists, under a main spring drive which is ratchet driven. The timing part is basically a lock and unlock lever mechanism which locks and then unlocks the gear train, this is known as the escapement. The escapement mechanism is connected to a device which either swings, the pendulum, or oscillates, the oscillating or timing wheel. As the pendulum or oscillating wheel swings or oscillates, the escapement is driven one way then the other to unlock and then lock the main drive gears which turn then stop on unlock to lock. When they turn they move the hands. The locking and unlocking causes the ticking noise heard during the escapement action. The wheels are numbered 1 to 5 and the hands are connected to only 2 of them. The hour hand is connected to the first or main wheel and the minute hand is connected to the 3rd wheel. In older clocks there isn't a second hand at all. In most antique clocks there was no mainspring at all but a system of heavy weights was employed as the driving force on the mechanism.In the 18th and 19th centuries the general rule of thumb was that all clocks were wound on a sunday, in fact there were clock winders employed in larger Cathedrals and Churches to reset the weights of the clocks for the start of the week. This was because the clocks of the time when wound fully only lasted a week before they required winding again. These antique clocks are generally called 8 day mantle clocks for that reason. I hope that this helps you.

Answer 2

Working Of A Clock

Answer 3

Frequency of the timing mechanism, essential for the clock to be accurate. The mechanism varies by type of clock (can be digital, atomic, pendulum....).

Answer 4

Which clock??
Granpa...
Quartz
Re-keying
Kinetic
Auto
Digital

The only common thing between them is the gears that move the needle, spare the last on please!!!
