Who invented the 6 simple machines?

Answer 1

1. The Pulley- Probably the earliest lifting pulleys used a rope over tree branch to lift heavy objects. Although pulleys were in use around the time the pyramids were built there is no record of them being used in their construction.

The first pulley systems built for lifting would have been made of tree trunks or branches with the rope over the horizontal part of the system. The use of wheels was the next step in the history of lifting pulleys

As people needed to transport goods over longer distances they discovered sails that used the power of the wind. To be able to use the wind power the sailors had to be able to raise and lower the sails. Pulleys were ideal for this task.

About 1100 AD the building of large churches called cathedrals became popular. These buildings were very large and some were around 150 meters high. Huge blocks of stone had to be lifted to build the walls and spires. The cathedral builders were the same people who designed and built the pulley systems to lift the blocks of stone.

2.The lever- Levers are one of the basic tools; they were probably used in prehistoric times. Levers were first described about 260 BC by the ancient Greek mathematician Archimedes (287-212 BC). Many of our basic tools use levers, including scissors, pliers, hammer claws, nutcrackers, and tongs.

3.The Wedge- History is not clear since it has been around for around 9,000 years. Almost all known ancient civilations had their version of the wedge.

4.The Wheel and Axle- The wheel is probably the single most important invention of all time. The oldest wheel was found in a place that is now called Mesopotamia. It is believed to be over fifty-five hundred years old. Before that time, people did not have wheels to move heavy objects. Axles were used to unite two or more wheels in order to achieve more work or transportation done.

5.The Inclined Plane- The inclined plane is one of the simple machines of antiquity, the physical operations of which were first theorized by Archimedes in the second century B.C., and then further explained by Hero of Alexandria in the first century A.D.

6.The Screw- Around the first century, screw shaped tools became common, however, historians do not know who invented the first. Early screws were made from wood and were used in wine presses, olive oil presses, and for pressing clothes. Metal screws and nuts used to fasten two objects together first appeared in the fifteenth century.

Answer 2

The first use of simple machines was probably the lever. Cavemen moved rocks using a tree branch as a lever to roll the rock.

List the simple machines and it will probably become evident the first use of simple machines.

Answer 3

The inventors' identities are lost to history. As an example: the first use of an inclined plane could be attributed to the first animal that rolled something up a hill.

Answer 4

MechanicsArchimedes and other ancient people with specific needs invented the 6 simple machines.
