There are six simple machines:

1. **Lever:** A lever is a rigid bar that pivots on a fulcrum. The ideal mechanical advantage (IMA) of a lever is calculated by dividing the length of the effort arm by the length of the resistance arm.
2. **Wheel and axle:** A wheel and axle is a combination of two wheels, one larger than the other, that are connected by a rod. The IMA of a wheel and axle is calculated by dividing the radius of the larger wheel by the radius of the smaller wheel.
3. **Pulley:** A pulley is a wheel with a groove around the edge, over which a rope or chain can be run. The IMA of a pulley is calculated by counting the number of supporting ropes.
4. **Inclined plane:** An inclined plane is a flat surface that is sloped at an angle. The IMA of an inclined plane is calculated by dividing the length of the inclined plane by the height of the inclined plane.
5. **Wedge:** A wedge is a two-sided inclined plane that is joined together at a point. The IMA of a wedge is calculated by dividing the length of the wedge by the width of the wedge at its base.
6. **Screw:** A screw is a rotating inclined plane. The IMA of a screw is calculated by dividing the distance between the threads of the screw by the circumference of the screw.

**Ideal mechanical advantage (IMA)** is a measure of how much a simple machine multiplies the input force. It is calculated assuming that there is no friction or other losses of energy in the machine. In reality, all machines have some friction, so the actual mechanical advantage will always be less than the IMA.

Here is a table summarizing the six simple machines and their ideal mechanical advantages:

| Simple machine | Ideal mechanical advantage (IMA) |
|---|---|
| Lever | Length of effort arm / Length of resistance arm |
| Wheel and axle | Radius of larger wheel / Radius of smaller wheel |
| Pulley | Number of supporting ropes |
| Inclined plane | Length of inclined plane / Height of inclined plane |
| Wedge | Length of wedge / Width of wedge at base |
| Screw | Distance between threads / Circumference of screw |

Simple machines are used in a wide variety of applications, from simple tools like crowbars and wheelbarrows to complex machines like cars and airplanes. They make it possible for us to do work that would be impossible or very difficult to do without them.<|im_end|>

**Real life examples of complex machines that make use of simple machines:**

| Simple Machine | Complex Machine | Example |
|---|---|---|
| Lever | Car Jack | A car jack uses a lever to lift the weight of a car. |
| Wheel and Axle | Bicycle | A bicycle uses wheels and axles to propel the rider forward. |
| Pulley | Elevator | An elevator uses a system of pulleys to lift and lower people and goods. |
| Inclined Plane | Staircase | A staircase is an inclined plane that allows people to move between different levels. |
| Wedge | Knife | A knife uses a wedge to cut through food and other materials. |
| Screw | Corkscrew | A corkscrew uses a screw to remove corks from wine bottles. |

Here is a more detailed explanation of each example:

* **Car jack:** A car jack is a lever that is used to lift the weight of a car. The lever is placed under the car, and force is applied to the long end of the lever. This force is amplified and transmitted to the car, lifting it up.
* **Bicycle:** A bicycle is a complex machine that uses a variety of simple machines, including wheels, axles, gears, and levers. The wheels and axles allow the bicycle to move forward, while the gears and levers allow the rider to pedal and control the bicycle.
* **Elevator:** An elevator is a complex machine that uses a system of pulleys to lift and lower people and goods. The pulleys are attached to a cable, which is wrapped around a drum. When the drum is rotated, the cable pulls the elevator car up or down.
* **Staircase:** A staircase is an inclined plane that allows people to move between different levels. The inclined plane reduces the amount of force required to move the person up or down.
* **Knife:** A knife is a wedge that is used to cut through food and other materials. The wedge shape of the blade concentrates the force applied to it, allowing it to cut through the material.
* **Corkscrew:** A corkscrew is a screw that is used to remove corks from wine bottles. The screw is inserted into the cork and then rotated. As the screw rotates, it moves into the cork, pulling it out.

These are just a few examples of how simple machines are used in complex machines. Simple machines are essential to many of the technologies that we rely on every day.<|im_end|>
