Westminister Chime
TRUE or FALSE: Time on the world's largest clock tower " BIG BEN " is kept accurate by a single penny...?
At an astounding 315 ft. {16 stories} with four clock faces (23 ft)
in diameter at 55 metres (180 ft) above ground and a clockwork
mechanism weighing over 5 tons, " BIG BEN " at the north end
of the palace of westminister in London, England is quite a sight
to behold .....
But what many do not know is that the reliability of keeping accurate
time on the world's largest chiming clock tower is done by
A SINGLE COPPER PENNY
which when placed upon the pendulum will change the
centre of mass and increase {or decrease if removed } the rate of the
swing of the pendulum by 0.4 second per day...

True or False
***
This is True for the Great Clock of Westminster. Of all the the bells within the Great Clock of Westminster, Big Ben is its largest bell.
The addition or removal of the penny weights changes the center of mass of the clock's pendulum.
