Simple machines help people lift and pull heavy objects. Simple machines like pulleys have been around for decades helping people work more efficiently.

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.
The wedge is one of the six simple machines and may have been the first or second developed (along with the Lever. When early humans made scrapers, axes and knives from stone, they were making a wedge.

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.

Perpetual motion machines have, to date, always been a disappointment.
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.
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.
