Okay kiddo, let's talk about maintenance engineering. Maintenance engineering is like taking care of a toy to make sure it's always working properly. Just like how mommy and daddy take care of the car by making sure the oil is changed and the tires are good, maintenance engineers take care of big machines and buildings to make sure they work properly too.
They do this by checking and fixing any problems with the machines or buildings. They look for things that might be broken or not working like they should be. They also create plans to keep things from breaking in the future.
Think of it like taking care of a garden. Just like how you water the plants and pull out the weeds to keep the garden healthy, maintenance engineers keep big machines and buildings healthy too. They make sure things are maintained and working properly, so everyone can use them safely and comfortably.
