Levers have existed since prehistoric times. There is no record of who invented levers. The earliest mention of levers of which there is a record was by Archimedes, but they were in use long before his time.
Archimedes discovered the concept of gravity with his levers and pulleys, his theory of displacement and invented the screw.
Pulleys and levers have been used in various forms for centuries, with evidence of their use dating back to ancient times. The precise origins are unclear, but they were likely developed independently by different ancient civilizations for tasks such as construction, transportation, and agriculture. The principles behind pulleys and levers have been refined and applied in numerous inventions since then.
The absence of levers would make it difficult to lift heavy objects, affecting activities like construction, transportation, and manufacturing. Machines like seesaws, wheelbarrows, and shovels that rely on levers for efficiency would not work as effectively. The overall efficiency and ease of many manual tasks would decrease.
