The Great Clock's pendulum bob (Big Ben)

[Fly0High]

how long is the frequency of the pendulum? I've counted about 2 seconds. does anyone have an exact mesurement?

[ZeroGhostDog]

It's almost like a heart...

The pendulum is real and it is on the Big Ben

May we see the clock movement?

Surprised the pendulum bob is only 93 lbs.

Is the pendulum heat and cold compensated?

Thank you.

I heard that the Pendelum is so sensitive, it can be modified for seconds per hour by adding a penny to one side.

[Cindermakers]

You heard wrong.

[imooreory]

hes right

[imooreory]

yes your right. you can see it in one of the other vids,

[glevantino]

yes, the rate the clock ticks is adjusted by adding or removing pennies the top of the pendulum, effectively changing the length of the pendulum. 1 penny changes the speed by .4 seconds per day!

@robertgift Where did you read the pendulum is only 93 lbs? The information text says it weights 203 kg, that is 447.5 lbs.

It's so small for something so big.

like how far down is it from the bottom of the pendulum?

@reevesc1986 The worst breakdown was in 1976 when part of the chiming mechanism disintegrated through metal fatigue. It caused a great deal of damage, and the Great Clock was shut down for a total of 26 days over nine months - the longest break in operations since it was built.
