There's a really good book called
Structures about the basic physics/engineering of keeping things from collapsing. Highly recommended. It taught me the coolest mechanical engineering fact I know, which is that the weight of a bike actually hangs down from the top of the wheel and is suspended by the spokes. If you have a bike sitting still and sever the bottom spokes of the bike wheel, nothing happens, but if you cut the top ones, the bike will fall down.
Wagons and carriages work the opposite way!
