Simple Machines (engineering)
A simple machine is a mechanical device that can help you change the force applied to help do more work easier. There are six simple machines: Wheel and axle, pulley, inclined plane, wedge, and screw.

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 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.
WHAT simple machines makes the computer works?
Computers don't have many moving parts.
A simple machine is defined as a mechanical device that changes the direction of force. Simple machines inside a computer would be the gears that enable an electric motor to rotate the hard drive and the gears that open and close the disc tray.
What simple machines is a fulcrum used for?
A fulcrum is used for the simplest of all machines - the lever.
What are the function of all the 6 simple machines?
Lever is used for lifting things like a wheel barrow
Wheel & Axle is used for moving things with less force like a bike
Pulley used for lifting and lowering objects like stage curtains
Inclined Plane is used for lifting/moving item onto a higher object like a ramp
Wedge is used for splitting/cutting like a wedge or zipper
Screw used for building and holding things together like bolts or screws
What simple machine is a roller skate?
Roller blades are a type of skates that use multiple wheels linearly aligned. They contain the simple machines of the wheel and axle.
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 all the simple machines to elevators?
I only know one simple machine which is the wheel and axle sorry! :(
What kind or a simple machines is a fan belt in a car?
A fan belt is a type of simple machine that uses the pulley system. That is how the belt gets turned by the wheels.
What kind of simple machine are in water well?
a wishing well is more than one simple machine. it could be a wheel and axle, or a screw depending on if it spirals down.
What is made of two or more simple machines?
What is made up of two or more simple machines?
There are only six different types of simple machines. The six simple machines are as follows: a pulley, a wheel and axle, An inclined plane, a lever, a wedge, and screw.
One of them is a pulley. A pulley is a wheel with a groove along its edge, for holding a rope or cable. It helps change the direction and point of application of a pulling force. Pulleys are usually used in sets designed to reduce the amount of force needed to lift a load. The magnitude of the force is reduced, but it must act through a longer distance. Consequently, the amount of work necessary for the load to reach a particular height is the same as the amount of work needed without the pulleys.
Well you know what I don't have the time to explain all of them to you so go somewheres else and look them up OK, OK goodbye. See you later. Peace out.

What simple machines make up complex machines?
A complex machine is a machine using more than one simple machine for its operation. A bicycle is a complex machine, using a lever for steering (handlebars), wheel and axle, inclined plane (the threads on bolts), and a pulley (chain on sprockets).
What other simple machines make up a wedge?
There is 6 simple machine theres screw,lever,pulley,wedge,fulcrum,inclined plane thats all
What are some current applications of simple machines?
i don't know if somebody know it tell my ok¿?¿?
What type of simple machines-gears can you find in a kitchen?
knife, bottle cap, broom, mop, sink handle, sink, oven door, fridge door, can opener, cheese grater, blinds, pizza cutter
What 2 simple machines make up a wheel barrow?
A wheelbarrow is made up of:
1) Two levers (The handles)
2) A wheel and axle
3) you may also roll it up An inclined plane
A wheelbarrow is an example of a class 2 lever and a wheel and axle.
A wheel and axle

What simple machines are in a faucet?
The simple machines in a faucet are: # A wheel and axle. # A lever (the handle). # Gears (probably inside the faucet). I'm pretty sure these simple machines are in a faucet, but I'm not sure if there are others. I've never looked into a faucet before...so, no experience. Thanks for reading my answer!
What kind of simple machines is a washing machine?
a washing machine means that wash the clothes . simple machine that makes work easy
If you are using a combo washer, there is the dryer. You will be amazed of the numerous features of washers today. You might be able to find a sensor in it as well. These sensors work in detecting sud or moisture content in your laundry. This helps a lot in conserving energy and water.
Wheels and belts.
wheel & axle, lever
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
What are 4 machines that use gears?
Almost anything that has mechanical movement. Cars, pencil sharpeners, electric drill.... the list goes on and on.
How changing direction of force makes work easier?
A simple machine makes work easier by reducing the force which it takes to move something. Also it makes life eaiser, but taking shortcuts does not always help.
