My name is M.Kalpana
I am studying seventh standard
in Nallampakkam panchayath union middle school.
I am here to say about Archimedes law of Lever
Archimedes principle of lever has three laws
The first law is similar to the way we use scissors
By using this principle, it is very easy to lift even heavy rocks.
Now, the second law is,
Take this weight and place this at the centre.
Now this is the second law.
This law is used to lift objects such as jalli (small rock material which is used for concrete) in constructions.
And this is second law.
