Underframe

Imagine you have a toy car and you can see the wheels and the body of the car. But there's something you can't see that's just as important - the underframe. The underframe is like the skeleton of the car, giving it structure and helping it move smoothly.

In real life, cars and trucks and even trains have underframes too. They're usually made of metal and they run along the bottom of the vehicle. The underframe holds everything together and keeps it from falling apart.

Sometimes the underframe of a vehicle gets damaged, especially if it hits something like a pothole or a bump. Mechanics can fix it by welding or replacing parts of the underframe. Without a strong underframe, a vehicle might not be safe to drive or might not work well. So, it might seem small and hidden, but the underframe is actually really important!
