Simple machines examples with pictures

However, break them down to their smallest parts and you're left with simple machines: Simple machines magnify, spread out, or change the direction of force, making it easier to move, cut and bind objects. Up and Down An inclined plane is a flat surface where the beginning and endpoints are at different heights and function by spreading work over a long distance. Some examples of inclined planes in your home are ramps and staircases.

See the Top 10 Questions Once upon a time a person needed to move something heavy. He or she picked up a long stick and stuck it under the edge of the heavy object and then pushed down on the other end of the stick. And the first simple machine was invented. Simple machines are just that.

The simplest form of using one thing to accomplish something faster or better. They were the first ones created and we still use them today. There are 6 basic simple machines; the leverthe wheel and axlethe inclined planethe wedgethe pulleyand the screw. Several of these simple machines are related to each other.

But, each has a specific purpose in the world of doing work. But what is work? Work is the amount of energy necessary to move an object. The further you move it, the more work is required.

Work is measured in Newtons. More about that later. The Lever The lever is a long tool such as a pole or a rod put under an object to lift it. The lever is more efficient when combined with a fulcrum. The fulcrum is another object, perhaps a rock, used to brace under the long tool.

This gives the long pole something to push down against. The location of the fulcrum helps determine how well the lever will perform work.

The closer the fulcrum is to the object being lifted, the easier the person can lift the object. The longer the lever, the higher the object can be lifted. Levers are all around us. Some examples of levers are: But it really would not work as well as it does had it not been for the axle.

An axle is a rod or pole centered in the wheel that allows the wheel to turn around it. The wheel then spins in a balanced circle to be used as transportation on a bike or to turn the hands of a clock. Gears are a form of the wheel and axle.

Wheels are found where things turn in a circle such as an electric fan, a motor, a revolving door, a merry go round, and any wheel — on the car, on your skateboard, or on a bicycle.

The Inclined Plane The inclined plane is simply a ramp. One end is higher than the opposite end. This allows things to go from a low point to a higher point. It takes the same amount of work, but less force, to move an object up a ramp than to move it vertically. Gravity makes it easier to move an object down a ramp than up that ramp.

Ramps are used in skateboard parks, wheelchair ramps and to get heavy equipment in and out of the back of trucks. But a modified version of a ramp is also found in stairs, escalators, ladders, walking paths, even chutes used for dropping your mail into the mailbox.

The Wedge Some people might see the wedge as just an inclined plane, although it is actually two inclined planes. However, the use of a wedge is actually different in nature.

The wedge is used to separate an object apart. This is needed to cut, tear or break something in two. A wedge can also be used to keep things together or secure things from movement.

Some examples of wedges that are used for separating might be a shovel, a knife, an axe, a pick axe, a saw, a needle, scissors, or an ice pick. But wedges can also hold things together as in the case of a staple, push pins, tack, nail, doorstop, or a shim.

The Pulley The pulley is actually a version of a wheel and axle that is combined with a rope, chain or other cord to allow moving something up and down or back and forth.

The pulley can be combined with other pulleys to reduce the amount of work necessary to lift huge amounts of weight or to lower them down.Common examples of simple machines include the hammer, crowbar, knife, log splitter, scissors, light switch, door knob, escalator, ladder, screwdriver, ramp, stairs, car jack, curtain cord and steering wheel.

The six types of simple machines include the wheel and axle, inclined plane, simple lever. 7 rows · Simple machines make work easier for us by allowing us to push or Type: Example: Activity: 1.

Pulley - How Stuff Works. A pulley is a simple machine that uses grooved wheels and a rope to raise, lower or move a load. 3. Wedge - pictures using LEGO bricks. A wedge is an object with at least one slanting side ending in a sharp .

Machines, simple A simple machine is a device for doing work that has only one part. Simple machines [1] redirect or change the size of forces, allowing people to do work with less muscle effort and greater speed, thus making their work easier.

A machine is a tool used to make work easier. It can do so by changing the direction of a force, increasing the distance or speed of a force, transferring a force from one place to another or increasing the magnitude of a force.
