Machines samuel, rodrigo and martín

Simple machines have few moving parts and include levers, inclined planes, screws, wheels, wedges, and pulleys. Complex machines are made up of combinations of simple machines and use various energy sources like human, electric, or fuel power. They are used for tasks like cooking, washing clothes, and calculating and include appliances, vehicles, and robots. Robots have advantages over humans in that they can perform quickly and handle dangerous jobs. Bicycles are an example of a complex machine made up of simple machines like levers, wheels, and pulleys that uses human kinetic energy through pedaling.

Simple machines have few or no moving parts. Some examples are: pulley, inclined plane, screw, wheel, wedge and lever.
It is a rigid bar with a support called fulcrum.
It moves objects up or down.
It uses a wheel and a rope to lift or lower an object.
We use a wedge to cut objects
It holds things together or lifts objects.
It turns around an axle. We use it to lift or move an object.
Complex machines are made up of a number of simples machines working together. Complex machines use energy to work. This can come from : people, electricity or fuels. We use complex machines everyday. Complex machines are everywhere.
Some examples are: washing machines, cookers and calculators. Which energy do they use? They use electrical energy and some use batteries. Some use solar energy.
Some examples are: cars, buses, lorries, bikes, etc. Which energy do they use? They use fuels like petrol or diesel but bikes use kinetic energy.
What do we use them for? We use robots to make mass-produced products. What are the advantages of robots? Robots can be quicker than us and they can do all the dangerous jobs for us.
A bicycle is a complex machine that needs our kinetic energy to work. We push the pedals with our feet, and when the pedals turn around, the wheels of the bicycle turn around, too. It is made up of several simple machines: Levers, wheels, pulley and a chain.
The handlebars are levers gear controls brake levers The brakes are levers The gears are pulleys tyre The pedals are levers back wheel front wheel
