As I noted previously, I already have the math posted and timestamped elsewhere on the net under this same username, and I have promised to present it just as soon as someone makes a mathematical argument which demonstrates some semblance of understanding of the physics involved. Absent that, presenting the math would be pointless, and while credentials you list suggest you have been exposed to the necessary understanding, as long as you insist on refuting my position verbally rather than mathematically, I'm going to stick to responding in kind.Originally posted by: DrPizza
I teach physics. I am a calculus professor. I majored in ceramic engineering (materials engineering) at Alfred University - the #1 school in the world for ceramic engineering at the time. Before you dismiss that engineering field as being irrelevant, consider that it requires extensive knowledge about the mechanics of materials, loads, etc. Subsequent to that, I decided to return to school to major in applied mathematics. I graduated summa cum laude & was ranked #1 in my university during my junior year. My conceptual understanding of physics is exceptional. Please, make with the math.
The only reason you're not presenting this info is because you don't have it. Quit playing games with us.
Anyway, try your suggestion with multiple cans spaced apart from each other and with a board on top of them to stand on. Then try that again with a few additional stacks of the same setup on on top of each other. Then try gluing those cans to the boards so they have lateral support. Then try to get all that to come down with a period of free fall by lighting a fire in it. You could put it all in a blast furnace for that matter, you still aren't going to get free fall.
Lets assume each can can support the weight of a man let say 200 pounds and we build your structure 4 level high with 4 cans on each level. The structure should be able to support about 800 pounds. Now eat up one of the cans until it fails, your structure will lean to one side and crumble at free fall speed. Why? because once the collapse starts, the cans are out of alignment and provide negligible support. This is comparable to the fact that a straw can be strong standing on its head but loses all strength once its bent.
This has been explained to you several times in this thread.
