Lever and pulley
the pulley was invented in ancient Sicily around 250 BC. The ancient Egyptian wooden four lobe pinion pulley was used to construct the Giza Pyramids around 2600 BC. This pulley surrounds its load and is unlike anything in the modern world. It operates with a mechanical advantage of 2.8 (MA=2.8) on the CLASS 2 lever principle. When hoisted the pulley with load rotates and climbs stepped structures with positive engagements of pulley lobes with steps. This is earliest machine known using "rack and pinion" mechanical technology. Google four lobe pinion pulley
Archimedes made many things. He made (invented) the Archimedes screw which helps farmers with their irrigation. He also supposedly made Archimedes Death Ray (which is a myth) and Archimedes Claw which is said unrealistic by modern engineers.
A keyed shaft or Keyway is method, based on a machined keyway in shaft, to attach something to the shaft and associated bore. A fitted key is inserted into a slot that is machined into the shaft. Although a machined keyway does result in a weaker shaft, it has it's applications. As in a lawn mower engine shaft. Theoretically the key will give way and save the shaft if you hit something with the blade. The negatives of a keyed shaft are that it can be deformed over time and result is a loose drive.

Make sure the key is the correct size for the keyway on both the shaft and pulley. Insert the key into the keyway on the shaft. Slide the pulley onto the shaft, ensuring that the key fits snugly into both the keyway on the shaft and the pulley.
No, The Greek Scientist who founded the Lever and Pulley is Archimedes.

A lever is an adaptation of a stick or tree branch. A pulley is an adaptation of a wheel.
