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.

Which of the following is a simple machine check all that apply?
A brick isn't a machine. The others are all simple machines; the only one that's not called by the same name is the screw (which is a form of inclined plane).
How do you make a simple machine windmill?
1.
- 1
Take the propeller off the flower. The flower's propeller will be used to spin the axle. A propeller from a larger pinwheel flower is best.
- 2
Place the spools between the plastic sheets and glue them on. These small spools should go at the corner of the plastic. Use super glue to attach the spools, and let it dry. This will serve as the casing for the windmill generator.
- 3
Measure the metal rod and drill holes in the plastic. The metal rod will go through the hole. Make sure the holes are perfectly aligned on both sides. Place the rod through the holes in the plastic.
- 4
Place the magnets in the casing. They should have enough space to rotate freely around the axle that will spin the magnets. Attach the magnets together using spacers. If there is not enough space between the spacers to insert the axle, the magnets are useless to generate electric current.
- 5
Put the rod in the hole. Wrap the wire around the generator. Wrap the wire around the casing 225 to 300 times.
- 6
Attach the propeller to the axle. The propeller from the wind decoration should be large enough to catch the wind. Place the propeller on a metal rod, and apply superglue.
- 7
Remove insulation from the wires. Attach the leads to the end of the low voltage and amperage light bulb.
- 8
Place the generator in a breeze. See if the wind can provide enough power to light the bulb. (If there is not enough wind, electrical current can be generated by manually spinning the axle rapidly.
Tips & Warnings
- Because the wind is not always available, the propeller may not rotate the magnet quickly enough to light even a small electrical light bulb.
What simple machine would be useful to get supplies up to a tree house?
Use a pulley and a rope and a flat piece of wood or a bucket:)
How is a screw used in every day life?
Screws are holding together the technology you're using you asked this question on. If you're sitting in a chair, there's a good chance screws are holding you up.
What simple machines are in a hot air balloons?
inclined planes - There has to be a screw or machined bolt in there somewhere.
lever - They pull on a lever to release the gas.
When a simple machine increases the force you exert what other factors change?
The distance of the object
Is a bicycle and a vacuum cleaner simple machines?
Neither of them are simple machines. A vaccum cleaner is composed of several simple machine, (I don't really know what) and a bicycle is composed of a wheel and axle (the two wheels), pulleys (the gears), and levers (Brake handles and pedals).
What kind of simple machine is a rowing oar?
It's a 2nd order lever. Water is pivot, boat is load, arm is effort.
An oar is a lever
What is Force you put into simple machines?
Tension is the force being used in Simple Machines. As well as simple machines may have a little gravity used, tension is the most used.
Give examples of complex machines and simple machines?
Well complex machines are usually hard to assemble and some times electronic like an xbox a microwave ect. A simple machine are usually made up of gears and wires like a clothes line a yo-yo ect. hope this helps
When you let water into a bathtub what kind of machine helps you open the tap?
It depends on the faucet but generally it would be a screw or lever.
3 ways simple machines make work easier?
Machines make work easier by:
-Changing the amount of force you exert
-Changing the distance in which you exert your force
-Changing the direction in which you exert your force
Work and simple machines answer sheet?
The fulcrum is the part of a lever that does not move.
The effort is the name of the force applied to a lever.
The load is the weight of the object being lifted by a lever.
How do simple machines affect your daily lives?
A scissors is made of levers and wedges. Cars, skateboards, and bicycles have wheels. Handicapped ramps are inclined planes. Screws hold our furniture together and hold our houses together as well.
Which of the six simple machines is the basketball hoop?
A basketball hoop could be several types of simple machines. There are actually more than one simple machine that I can think of. The ones I can think of are the lever, the pulley, and the wheel and axle! Those are the ones I can think of.
What type of lever are knives?
The knife is a third class lever. The pressure is applied to the other end of the handle nearest to the blade and the fulcrum is at the end of the handle nearest to the wrist.
