The mechanical engineering and math test assesses knowledge of various engineering disciplines and the ability to solve mathematical problems.

The assessment includes work-sample tasks such as:

- Properly dimension electrical elements in an electric circuit.
- Understand the behavior of materials under different temperatures.
- Solve linear equations to calculate variables.

A good mechanical engineer needs a solid understanding of engineering physics, mathematics principles, and materials science in order to design, analyze, manufacture, and maintain mechanical systems effectively.

## Sample public questions

Before purchasing seeds, a farmer needs to know the area of his land. Since one end of his property is currently unapproachable, he measured only three sides. This is his sketch with measurements:

What is the area of the land?

A company is developing a temperature alarm, based on the schema below, that should close an electric circuit when the temperature rises above 150°C:

Linear coefficient of thermal expansion (x10^{-6}K^{-1}) |
Volumetric mass density (kg/m^{3}) |
Melting point (°C) | |
---|---|---|---|

Brass | 13 | 8600 | 1000 |

Copper | 17 | 8940 | 1100 |

Iron | 11.8 | 7870 | 1500 |

Mercury | 181 | 13540 | -39 |

Polystyrene | 70 | 1060 | 100 |

Steel | 12 | 7800 | 1600 |

Based on available materials and their properties, choose materials for the temperature alarm that require the smallest temperature difference to do the task.

For Material 1: ___

For Material 2: ___
