420 - What is mechanical engineering, and what do mechanical engineers do?

Imagine you have a toy car. It has wheels, an engine, and breaks. All the parts of the car work together to make it move. Mechanical engineers are the people who design, build, and fix machines like cars, robots, and even roller coasters.

They make sure the machines work properly, are safe to use, and are energy-efficient. Mechanical engineers design the parts of the machine, test them, and fix any problems that come up.
