## Studying Oreos Under Pressure

Contributors: Alan Quintana, Kirsten Liddle,& Sami Covis

### EXPERIMENT:

- To determine how much physical pressure an Oreo can withstand.

### MATERIALS:

- Four Oreos
- Text books
- Scale
- Meter stick

### PROCEDURE:

- Place four Oreos in a rectangular formation about the size of an everyday AP Physics text book.
- Stack text books on the Oreos until they crack
- Measure the height of the stack
- Weigh each text book used
- Find area of one Oreo
- Using P=F/A to determine the pressure that the text books exerted on each Oreo
- Repeat using four stacks of two Oreos on each corner
- Measure height of Oreo before and after experiment

### DATA:

- Data table 1 shows data recorded for a single layer stack of Oreos

Area (m^{2}) |
Force (N) |
# Books |
Stack Height (m) |

.0016 |
811 |
39 |
1.49 |

- Data table 2 shows data recorded for a double layer tack of Oreos

Area (m^{2}) |
Force (N) |
# Books |
Stack Height (m) |

.0016 |
924 |
44 |
1.72 |

### RESULTS:

- Using the equation P=F/A the pressure on each Oreo can be calculated.
- The single layer of four Oreos can withstand 506,875 Pa of pressure.
- The Oreos broke and the tower of books fell over. The Oreos compressed 3mm.

### POSSIBLE APPLICATIONS:

- Oreos can be used as building materials.
- School cheese can be used to cement the oreos together for an unbreakable foundation.
