Gravitational collapse with crushable supports between 2 in. diameter washers weighing approx. 1.7 oz. each. The thickness of the washers does vary, they are sorted so the thinnest at the top and thickest at the bottom. 3 of the thinnest are about equal 2 of the thickest. So the weights range from 1.4 to 2.1 ounces. The intermediate supports are loops of paper 9/16 inches tall. The top 11 supports are single loops. The next 17 are double loops and the bottom 5 are triple loops. The falling mass consists of 4 washers out of a total of 33 or 12%. So the falling mass can sustain damage just like the stationary stack.

I have tested the single loops for what was necessary to crush a loop. Dropping 4 washers from 4 inches will crush a single loop. It takes 0.1182 joules to crush single loop

The dowel is 4 feet tall and less than 3/4 in thick and there is nearly a 1/16th gap around the dowel to a washer. Some rubbing is inevitable.

Notice that loop 11 which is a single loop remains intact. So the collapse was not stopped because of double loops.

  • Well, it's that day. TEN YEARS of Bad Physics!

    The Physics Profession has not demanded accurate data on the distributions of steel and concrete down the towers. Who cares about Potential Energy and the Conservation of Momentum?

    I guess it is time to burn Isaac Newton in effigy.

see all

  • @flanksteak2 Some times I get slow days and can stoop to responding to REALLY DUMB STUFF.

    I don't look at this video much. There is one with a sound track and intro I stole from Ryan Mackey. I figured out in two weeks that it was ridiculous to think that airlines could destroy buildings 2000 times their mass in less than two hours.

    Unfortunately it is hysterically funny that the physics profession has not demanded accurate data on the distributions of steel and concrete in TEN YEARS.

  • @psikeyhackr You really think you have all this figured out don't you? You, the Youtube flunky, really truly believes he is onto something because you are a batshit crazy shizoid.

    7 months later.......LOL

  • @flanksteak2 So how can the math be done without accurate data to plug into the equations?

    Therefore anyone that understands the PHYSICS should be demanding the data before talking about math. So why don't we know the TONS of STEEL and TONS of CONCRETE that were on each and every level of the towers after almost TEN YEARS?

    Why hasn't the Physics Profession been demanding that information?

  • @Merlin5by5 {{{ Both the Impactor, and the Impacted, are being CONSTANTLY accelerated DOWN.

    That's what WEIGHT IS, your mass accelerated down at 1 g. }}}

    What insane physics! Being subjected to a force is not being accelerated by it. Acceleration is change in VELOCITY. If mass is stationary then it is not accelerating. 9.8 m/s^2 is the acceleration caused by gravity IF the mass is free to fall.

    These schools sure as fell let people pass with incompetently memorized physics. LOL

  • @naziballs

    LMAO, since when? Total Momentum is added to in a gravity field.

    Both the Impactor, and the Impacted, are being CONSTANTLY accelerated DOWN.

    That's what WEIGHT IS, your mass accelerated down at 1 g.

    That's what CONSTANTLY compresses the springs in a weight scale.

    There is a constant acceleration in a gravity field, and there is practically

    no place in the universe without a gravity field, even between giant

    galaxie clusters separated by millions of light years.

  • When any two bodies act upon one another, their total momentum remains constant provided no external forces are acting. In other words, we can say that whenever one body gains momentum, then some other body lose an equal amount of momentum, that is , momentum is never created or destroyed.
