Classification of Simple Machine
There are six types of simple machines:
- Lever: A lever is a bar that pivots around a fixed point, called a fulcrum. Levers can be used to lift heavy objects or to apply a large force to a small area.
- Pulley: A pulley is a wheel with a groove around the edge that is used to change the direction of a force. Pulleys can be used to lift heavy objects or to apply a force over a distance.
- Inclined plane: An inclined plane is a flat surface that is slanted at an angle. It can be used to lift heavy objects with less effort than lifting them straight up.
- Wedge: A wedge is a triangular-shaped object that splits or cuts materials. Wedges can be used to chop wood or to open cans.
- Wheel and axle: A wheel and axle is a combination of a wheel and a rod that rotate together. It can be used to lift heavy objects or to apply a force over a distance.
- Screw: A screw is a spiral-shaped object that is used to fasten things together or to lift
What Is a Simple Machine?
Simple machines are a fundamental aspect of technology and have been used throughout human history to make tasks easier and more efficient. They are mechanical devices that help us to perform work by applying a force over a distance, and they are classified into six main types: lever, pulley, inclined plane, wedge, wheel and axle, and screw. These simple machines are the building blocks of more complex machines and are still widely used in industry and everyday life.
