1 SIMPLE MACHINES By Michael Wegener

2 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.

3 The lever 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.

4 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.

The Incline Plane 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.

6 The Wheel and Axle 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.

7 The Wedge 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.

8 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.
