That was the reason behind the invention of
winches and pulleys that you  studied in physics.
Pulleys made life easier
Like all simple machines, the origin of the pulley system is unknown. It goes back to 1500 BC, to the
people in Mesopotamia who were using rope pulleys for lifting water.
Pulleys work by trading distance for effort and changing the direction of the force. For example, using
two pulleys to lift a weight, it only needs half the force to lift it as it would with one pulley, however if the weight was being lifted one
metre high, two metres of rope would be needed. This is called the ‘mechanical advantage' and can be
increased by adding more pulleys into the block and tackle system.
Pulleys were responsible for the invention of the crane. The first recorded cranes appeared in Greece around the late 6th century
BC, now it is a tool that most of us see on an almost daily basis.]]> 2022-04-25 08:16:31 UTC https://padlet.com/shraayazan6/u0cn3wdurjjfmrk8/wish/2156135620 shraayazan6 https://padlet.com/shraayazan6/u0cn3wdurjjfmrk8/wish/2156136132 2022-04-25 08:16:53 UTC https://padlet.com/shraayazan6/u0cn3wdurjjfmrk8/wish/2156136132 shraayazan6 https://padlet.com/shraayazan6/u0cn3wdurjjfmrk8/wish/2156136813 Examples of pulleys applications in our daily life:
- Sails on sailboats are raised and lowered using pulleys.
- Wells use the pulley system to lift the bucket out of the well.
- Curtains at a theatre are moved using pulley systems that pull the curtains apart.
- Escalators use pulley systems to function.

I will choose one of the pulleys applications from the context and explain orally how it works to a family member or a friend.
3. I will give examples of 3 English proverbs and explain them on a piece of paper.
