Simple Machines - The Lever
The fulcrum is a fixed point where the arm balances on. This is like the middle of the seesaw.
The arm is a plane that balances on the fulcrum. If you are lifting an object, it would go on the arm of the lever.
If there was something really heavy on this side of the lever, it would stay on the ground until the other side had enough weight to lift it up. Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube.
The load is the object on the opposite side of the force. It rests on the arm of the lever.
DID YOU KNOW? The closer the fulcrum is to the load, the easier it is to lift it.
Force is needed to lift an object. The force must go on the opposite side of the load, as shown in this picture.
The load is the object on the opposite side of the force. It rests on the arm of the lever.
WHAT IS A SIMPLE MACHINE? A simple machine is anything that can make work easier. There are six simple machines: the pulley, the wheel and axle, the wedge, the screw, the inclined plane, and the lever. A complex machine is a machine made up of one or more of these simple machines.
This is a game where you can virtually build and use simple machines. Game with challenges to create simple machines that help adorable-but-lazy Twitch do his work.
WHAT IS A LEVER? A lever is a type of simple machine that has a bar resting on a pivot. This is used to help move a heavy load on one end when force is applied on the other.
Levers are used to make life easier. Examples of them are: Scissors Catapults Seesaws Hammers Human Arms (very useful!) Handle Brakes on a Bike Staplers And many more!
