Simple Machines (engineering)

gears and wheel and axle

Simple machines are considered simple because they usually only have one part or need one force to work.

Self powered machines were first used at the start of the industrial revolution. Tabulating machines were known to the ancient Greeks, such as the famous Ankylothera Device. The Romans, too, had contraptions that moved and worked much as we might imagine modern machinery might, though not driven by piston engines. Some of these, such as the catapult, were known as engines of war. The water wheel is considered a fairly crude machine, and can was used to grind grain or wash clothes.

Archimedes invented a "screw" for irrigating crops, another clever early machine. The clepsydra, a water clock, could also be considered a machine.

1. Pulley-a simple machine that uses grooved wheels and a rope to raise, lower, or move a load.
2. Lever- a stiff bar that rests on a support called a fulcrum which lifts or moves loads.

The six simple machines are wedge, inclined plane, screw, the wheel and axle,lever and the pulley are the six simple machines.

The inclined plane (you'll see why I started with this first) is simply a ramp or slope that reduces the amount of effort force needed to move the load.

The wedge is two inclined planes put together back-to-back.

A screw is an inclined plane wrapped around a rod.

The wheel and axle is a circle attached to a rod.

A lever is a simple machine consisting of a rigid bar pivoted on a fixed point, called the fulcrum, and used to transfer the effort force in order to raise the load. There are three levers: Class 1,2,and 3.

Last but not least, the pulley is a grooved wheel with a rope or chain running through it. There are two types of pulleys: fixed and moveable. There are two systems, both consisting of pulleys: the block and tackle and compound pulley.

Hope this helped!

all 6 are the wedge, the pulley, the screw, the lever, the wheel & axle and the inclined plane. answered by a smart 5th grader:)

A complex machine.(I just did a school test on this and it said compound machine was correct, not complex)

a small crane made of pulleies and rope

What are three simple machines that are basically the same?

The bottom of a light bulb is a screw.

Cybernetics "the scientific study of control and communication in the animal and the machine." ― Norbert Wiener, Cybernetics: Or Control and Communication in the Animal and the Machine

It is a compound machine that is made up of a lever (the handle) and a wedge (the staples). Some internet sources include a wheel and axle (the pivot point for the handle) and an inclined plane (the slant for papers under the staple dispenser).

wheels- wheel axle

gear shift- lever

seat belt- pulley

mirrors- inclined plane

Shocks and brakes have wedges, and also screws hold the car together.

return them to their proper places

after use

use them only for purposes wherein they are needed

keep them away from children's reach

keep the tools in a tool box or cabinet

Just in case you're in a hurry, let me assist you by emphasizing that the key concepts of 'simple machines include: lever, screw, pulley, wheel & wheel axle, inclined plane, and wedge. So, from these everyday things you or you and your parents use, I have every confidence that you'll be able to categorize each correctly by yourself (smile) - - - which include (but are not limited to): Basketball Hoop, Door Knob, Doorstop, Drill Bits, Paper Cutter, BICYCLE tires/seats/chains brake(s), Hedge Clips, Wheelbarrow, Tape Dispenser, and Stapler.

Do you mean technological development? Then the answer is no. All complex machines are made up of simple machines in various combinations. Without the one, you can't have the other. The world would go on, of course, but the technological complexities of its modern civilizations could not exist without simple machines.

Are you looking for the types of simple machines or examples of each one?

The types are:

1. wheel and axle

2. lever

3. pulley

4. screw

5. wedge

6. inclined plane

An example of a wheel and axle is a wheelbarrow and a hamster wheel. A lever is a human arm and a hammer (which is also a wedge). A pulley is a flag pole and the string you use to pull on the blinds. A screw is a slinky and a literal screw. A wedge is a carpenter's plane (a tool carpenters and cabinent makers use to smooth their wood), knitting needles, a chisel, a hatchet, and so on. An inclined plane would be a ramp, slide, or hill.

All you have to do is fine a simple task to do and find simple machines and connect them together to make it. All you have to do is fine a simple task to do and find simple machines and connect them together to make it.

In artistic gymnastics you use a beam, bar, beam and floor and sometimes trampoline and vault. In Rhythmic gymnastics you use rope, ball, clubs, ribbon, hoop, and free (no equipment) all on a floor. # Uneven Bars # High Bar # Parallel Bars # Rings # Balance Beam # Floor Exercise # Pommel Horse # Vault Accessories:

# Chalk # Grips # Leotards # Warmups # tape # music (for floor routines) # Spring board (for the vault) # Springs (to go in the Spring Board) # Mats # Braces (knee, ankle, etc.)

Rollers are like other simple machine like pulleys and others.

I'd say the gears on a bike acts as levers, as pedals and driven wheel turns with different speeds and force.

A train is not a simple machine.
