Simple Machines Make Life Easy

Simple machines are machines with very few parts. How do they help us? The answer to that question is they reduce your effort that you would

actually need to actually lift the object. Ancient people may have started building these machines by watching animals, but nobody knows the true

answer except the individual being (or human beings) that built it. Since none of us are the originator of these amazing tools (or ones similar) why

the earliest ancient people built them will remain as a mystery to us.

An example of a first class lever is a seesaw. A example of a second class lever is a wheelbarrow. A example of a third class lever is a baseball bat. No matter what class lever you are using

you have a load, fulcrum, and a effort force. To build a wedge you would take a bar, a plank, or a pole and put something round

under it like a wheel or a pebble underneath your pole, bar, or plank. You would then take your load and place it on one end of

your pole, bar, or plank. Once finished with those you would push on the end of the pole, bar, or plank that doesn’t have the load. If

your load goes flying away you have made yourself your own lever.

The pulley

They help us people lift heavy things. They assist us by putting in work so we put in much in much less effort. What is they? They is the pulley. With out them there probably wouldn’t be any 10 story floor buildings! There are three different types of pulleys. One of them is the fixed pulley. When you pull down your load goes up. This works when a wheel is attached to an object that can’t move. Then a rope is rounded around the wheel and the other end of the rope is tied around

your load. When you pull the rope down your load will go up. The fixed pulley will not reduce the weight of your load. Another pulley is the movable pulley. It is

made by curving the rope around the bottom half of the wheel so when you pull up your load goes up The last pulley I am also sure of how to construct. It’s name

is the Fixed and Movable pulley. It is built by constructing two wheels to your positioned object with one long piece of rope so that when you pull down your

load goes up. In other words it is a fixed pulley combined with a movable pulley.

Inclined planes are flat, slanted surface. Movers use inclined planes to move their furniture when they move. Inclined

planes help us reduce the effort to move an object. This helps when pushing a 200 pound dish washer up a ramp after

putting it on wheels would be much easier than picking it up and carrying it out of a house and heaving it onto the back of

a moving truck that’s trunk’s floor is 4 feet off the ground.

The Incline Plane

Wheel and axles are worked by a force acting upon the wheel forcing the wheel to turn. When the wheel

moves the axle moves with the turning wheel causing the axle to turn as well as the turning wheel. So a few examples of wheel and axles are the screwdriver and

the Ferris wheel.

A wedge is two inclined planes back to back. Wedges change downward or forward which slices the item in half. A wedge converts motion in one direction into a splitting motion that acts as right angles to the blade. People may have got their idea of the wedge from the woodpecker.

Screw

The screw is a relative of the inclined plane. All it is a inclined plane twisted spirally around. You would not

have to turn a screw around a lot to turn it into a piece of wood. A screw increases your force so that is why it

can go deep into the wood.

The End!
