How do floors bend/shake but not break?

576 views

I’ve had a bizarre phobia since I was young. I do not trust the structural integrity of most buildings and am always worrying things will collapse/break. One thing that really triggers my anxiety is when I can feel a floor shaking. If my one year old, 25 pound son can run by and make the floor shake, how can it hold substantially heavier items (like a fridge, washer, etc.)? Please only reassuring comments – I can’t handle this phobia getting any worse 🙂

If it helps to ease your phobia, you might consider the vibrations you’re hearing and feeling as ripples on the surface of a pond. That’s pretty much what they are. When your son runs across the floor, what you hear and feel is those ripples traveling through the floor (and the air) and bumping into your body.

Have you ever seen a picture of [the inside of an acoustic guitar?](https://www.reddit.com/r/Damnthatsinteresting/comments/ivakd0/inside_of_an_acoustic_guitar_looks_like_a_luxury/) Check it out. It looks cool. That’s basically what your house is. If you rapped your knuckles on the “floor” of that picture, you’d hear quite a loud sound as the vibrations traveled around, but there would be absolutely no danger of your knuckles breaking through. You’d have to hit it incredibly hard with your fist to break through. And a guitar is very thin wood held together with only glue! Your house is made of, and held together by, much, *much* stronger materials.
