What are some animals that are examples of simple machines?
Technically, no animal is a simple machine. Simple machines are the basic elements which comprise all other machines. Though some people compare animals to machines and comparisons between anatomy and simple machines might be possible, they are far from obvious.
What are the six simple machines and how do they work?
There are many different types of machines in the world. Machines help people do work, and make it easier for them. There are six simple machines, and the rest are classified as complex. These six simple machines are: 1) Pulley 2) Screw 3) Lever 4) Inclined Plane 5) Wheel and axle 6)Wedge
Why are simple machines used?
they can help you like a pencil helps you write
What are two ways machines make work easier?
Machines make work easier because they help to increase productivity. An example of a machine is a forklift. Forklifts allow workers to move more materials at one time which lowers the amount of time it takes to move materials.
Who invented the 6 simple machines?
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 pulleysAs 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.

How did people do their work before they had machines?
they would make it by hand
What did people use before machines were invented?
They used only themselves.
How can machines be changed?
People are developing new machines all the time. Sometimes they do things that earlier machines could not do, or they may do the same things but with greater efficiency, greater speed, less cost, and so forth. We always try to make our machines better.
How is water processed before and after being used by people?
it cleans the water so humans can drink it.
