people have been using it forever
Simple machines help people lift and pull heavy objects. Simple machines like pulleys have been around for decades helping people work more efficiently.
200 years
Factories have been using machines since the Industrial Revolution, which began in the late 18th century, around the 1760s. This means that machines have been a part of factory operations for over 250 years. The introduction of machines significantly increased production efficiency and transformed manufacturing processes. Since then, the use of machines has continued to evolve with advancements in technology.
His knowledge surpassed simple machines. He conceptualised a helicopter, a tank, concentrated solar power and a calculator; to name but a few. Most people today would not have the faintest idea how a helicopter works and as for solar power, electricity had not even been invented yet and Da Vinci already had ideas for it.
A lever and a pulley are different. They are both simple machines that have been around for over two thousand years and described in detail by a Greek named Archimedes.

We use simple machines like the lever to make work easier by allowing us to multiply or change the direction of the force applied. Levers help us lift heavy loads with less effort by using a fulcrum to pivot and redistribute the force. Simple machines like the lever are fundamental tools that have been used for centuries to accomplish a variety of tasks with efficiency.

Yes and its not uncommon,a few people are killed every year when machines topple over on them.

Compound machines were not invented by a single individual. They have been developed over time by multiple inventors and engineers, each contributing unique components and designs to create more complex and efficient machines. The concept of combining simple machines to create compound machines has been used for centuries to solve various challenges and improve efficiency in tasks.
Perpetual motion machines have, to date, always been a disappointment.
The Yabbse software has been put to rest and re-branded "Simple Machines." The new software package is a free, professional grade of software that allows one to set up their own community. Information can be found at Simple Machines Forum.
