The Mechanical Engineering test assesses knowledge of mechanics, thermodynamics, materials science, and electricity through a series of numerical calculations and multiple-choice questions.
The assessment includes solving work-sample tasks, such as:
- Calculating forces acting on a mechanical system that functions as a lever.
- Anticipating how materials will change when temperature and pressure change.
- Understanding and improving electric and internal combustion engines.
Good automotive, industrial, or mechanical engineers require a deep understanding of mechanical principles to make knowledgeable decisions and effectively manage engineering challenges.
Sample public questions
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 (x10-6K-1) | Volumetric mass density (kg/m3) | 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: ___

What others say
Simple, straight-forward technical testing
TestDome is simple, provides a reasonable (though not extensive) battery of tests to choose from, and doesn't take the candidate an inordinate amount of time. It also simulates working pressure with the time limits.
