There is a relation between the crow
story what we heard in our childhoods
and the Archimedes principle
what we studied in school
Let us see in this video what those are...!
♬ ♫ ♩♪ SMART ENGINEERING ♩♪♫ ♬
We all heard a strory when we
studied Archimedes Principle
There is a King in country
He was intrested to make gold crown
He called a Smith
King gave him Pure gold
And told him to do the
crown in Pure gold
Next day, The smith made a Beautiful Crown
and give the crown to the king
At that time, a doubt was made to the king
Is the crown really madeup
of pure gold what we gave..?
Or there will be anything mixed
with gold like silver,...
At the time, King called
Archimedes and asked
Is this crown is made of
pure gold what I gave
or Is there any mixture in this crown..?
On the next day, when
Archimedes stepped into bathdub
He saw the water spilling out and Shoutted..
Eureka... Eureka...!
We all know the meaning for Eureka...
He said "I found It.. I found it.."
Now, to this story and our
childhood thirsty crow story
There is relationship
We all know the moral in
the Thrirsy crow story
Let us see the science in the story
Archimedes what he found
in the Bathdub is...
Volume of material immersed equal to
Volume of water Displaced
Meaning of this statement is..
 when Archimedes stepped into bathdub
Volume of the Water
displaced from the bathdub
is equal to the volume
of the leg he stepped
Like that, when submerge
his body in the bathub
Volume of the water displaced
is equal to volume of his body
From this only, Archimedes said that
there is a difference in volume
Infront of the king
The crown made by the smith was
put into a beaker full of water
and in another beaker the pure gold
given by the king was submerged
There is a difference betwwen the
water displaced in the two beakers
By this, Archimedes said that
there is a big scam in the crown
Incase the smith takes
10 gram of gold and..
add other materials like
silver for 10 gram
Here is the concept of density
Density is mass/volume
that is how much mass in an unit volume
for example
density of gold is
In a centimeter cube there'll be 19.32 gram
Like that, for silver there'll
be 10.5 gram in a cenimeter cube
Density of the pure gold and the drown
should be same
If the density differs, volume also differs
By this only, Archimedes said that
the crown is not madeup of pure gold
At once, the smith measures
volume of pure gold
and replaces the silver equal
to the volume of pure gold
Mass must be differed
finding inequalinty in
mass is not a tedious one
we can find it using a balance
Like this, In the crow story
when the crow put the stones in the pot
volume of water raised
in the pot is equal to..
volume of the stone
