# Mechanical Engineer

You design machines with moving parts, like engines and robots.

Machines work because of pushes, pulls, and energy. When you understand those, you can make an engine spin or a gear turn.

## The topics behind it

- [Pushes & Pulls](https://lightmysky.com/learn/science/pushes-and-pulls-mt_B3W5EfimJw): Pushes and pulls make every part of a machine move.
- [Efficiency, Sankey diagrams, and work done](https://lightmysky.com/learn/science/efficiency-sankey-diagrams-and-work-done-mt_JyfLtl_nhw): A good machine wastes as little energy as it can.
- [Predicting Motion Patterns](https://lightmysky.com/learn/science/predicting-motion-patterns-mt_AlLYwCm92a): You guess how a part will move before you build it.
- [2-D shapes](https://lightmysky.com/learn/mathematics/2-d-shapes-mt_KJeEeTutJI): Gears and plates start as flat shapes you plan out.
- [Iterative Design and Prototyping](https://lightmysky.com/learn/design-and-technology/iterative-design-and-prototyping-mt_fYD3KaViOZ): You build a rough model, test it, then improve it.
- [Choosing measurement units](https://lightmysky.com/learn/mathematics/choosing-measurement-units-mt_DOe893F6gN): You pick the right units to measure gears and parts to the millimetre.
