Heiwa's bathroom scale experiment

As JREF posters discussing the WTC1 collapse on the Pizza Box Tower thread don't know the difference between weight/mass (kg) and force (N) and moving bodies, let's do a new experiment in the bathroom in this thread and prove Bazant and NIST wrong, i.e. debunk them.

All you need is a bathroom scale! And a bathroom. And a ladder.

Assume you are in the bathroom and step on the scale and that it announces that your weight it 120 kgs (or what ever that is in US - 20 inches)! OK, you are only 160 cms (what is that - 3 lbs?) tall, so you are a small, fat weight, but who cares. Most Americans are overweight.

Actually the scale does not register your weight but the force (via a magic device inside the scale) you apply to the scale - in this case about 1180 N - and then it transforms this force into weight - 120 kgs. Ok, big belly but otherwise quite fit.

So far so good. Now the experiment. You are going to jump on the scale from 3.7 meters height and see, if your weight changes. Of course your bathroom has a high ceiling. Americans have big houses.

OK, get the ladder into the bathroom and step up to the 3.7 m level. Don't knock your head against the ceiling.

Now jump on the scale!! WOSH, BANG!

What is your weight? Still 120 kgs! The scale records the same weight.

Good!

I hope you survived the experiment, because you just simulated the upper block of WTC1 dropping on the lower structure that pulverized it on 9/11. You evidently didn't pulverize the scale as you survived and checked your weight. 120 kgs. Bathroom is still intact!

Now a lot of people will say that your weight changed, when you impacted the scale, but it was 120 kgs before and after the experiment, so why would it change in between?

Now a lot of people will object and say that the force on the scale was not 1180 N on the scale during the experiment. That is correct. It was 0 N before jump and 1180 N after jump/survival and checking the result. It thus changed from 0 to 1180 N.

But you will object again - it was >1180 N after contacting scale after jump and when you read the result on scale after survival.

OK, but you normally do not measure your weight by jumping from 3.7 meters on your bathroom scale! So whatever you measure then, was not your weight.

WARNING! As you are not very rigid, you may kill yourself, jumping on your bathroom scale. Actually, you will prove that the upper block of WTC1 would be destroyed, when impacting the lower structure (the scale) which is very good. R.I.P.

My scale has a tell tale that records max (momentary) load. My 200* lbs maxed out the scale (*350+). (I only jumped from less than one meter)
Now what?

My digital bathroom scales record - transiently - far more than my actual "weight" when I jump on them.

Congratulations - it took you 6 minutes to (not) carry out the experiment due faulty equipment. Let's hear from somebody really doing the jump with proper scale!

Pls do a proper experiment - jump from 3.7 m! And keep a sharp eye on the scale.

I just read DGM's quote.

Wow. Just wow.

Despite the fact that the act of slowing you to a stop (decelerating you) causes the scale to record a value much higher than your weight, Heiwa still thinks that balancing the forces will result in a change in velocity.


I call Poe.

Nobody can be this confused about the difference between static and dynamic situations.

Weight and mass aren't the same thing. Weight is a measurement of force.

Just for laughs I jumped on my old scale and it broke! It didn't break when I just stepped on it. How is this possible, Heiwa?

Pls, do the experiment ... and then post comment.

It seems DMG only jumped from one meter and managed to decelerate to zero velocity in order to survive. During deceleration/change/reduction of velocity DMG also managed to check the scale. Quite good. Now, let's do it from 3.7 meters.

But so far so good. Nobody has collapsed any scales or bathroom floors so far! Just carry on!

i have a plastic bathroom scale, if i jump on it from 3.7m im fairly certain i will break it, its a 60 dollar scale, so i wont be doing that, although if you paypal me th emoney for a replacement ill gladly jump on it from as high as i feel comfortable, i feel the result will be very significant to the discussion

it was my understanding that 120kg is a mass, and 1180 N is more accurately described as a weight (IE mass times gravity)

putting anyone on ignore does not make you any less wrong. It does not matter what posts you can see. It matters that everyone else can see us point out your fallacies for what they are.

It's self-refuting anyways.

Note how he lists weight with mass, and implies it is different than force.
Newsflash: Weight is a force measurement.

We don't need to jump 3.7 meters. We can just scale up our results. Just like you scaled down using pizza boxes.

I sure hope Heiwa hasn't propositioned any children to do this "experiment" (or anything else, for that matter). Frankly, this deranged freak shouldn't be allowed within 3.7 meters of a child.

I thought Heiwa's Pizza Box Experiment was unbeatable when it came to the "Idiotic, Crackpot Experiment" department, but he topped himself this time.
And I refuse to beleive he is any kind of Engineer.

dude. i majored in geography. even I remember from high school physics that an object's mass (and therefore force upon impact) increases with speed.

throw a ball at you at 6 mph. no big deal. throw the SAME ball at you at 90 mph?

OUCH!!!!

are the laws of physics different in truther-land then on Earth? it appears so.

Just to be clear, an object's mass does not increase with velocity (not unless it is going really, really fast, like approaching the speed of light).

It's momentum and the force that it would apply on another object does increase with velocity however. In this case, the weight (which is a measurement of force) that a scale reads when you jump on it.

Is this Stundie of the year? I tell you what Heiwa I'll jump from 3.7m onto some bathroom scales and post it on youtube if you do the following experiment first.

Place a 5kg weight on your head. Then drop the same 5kg weight from a height of 1m (you can do 3.7m if you like) onto your head. Record your results and post on youtube. You shouldn't come to any harm should you? If not, why not?

Well, not quite. Rest mass is a constant, but the momentum will change with speed.

Unless you were talking about relativistic mass...

Is this a ploy to give Richard Gage's cardboard box experiment more credibility?

I remember doing this with an old scale when I was a kid, by jumping on the scale, or pressing down on the scale, I wanted to see how high it would go.

An excellent example of what force can do vs the weight are meteorites. They don't have to weight much (Lets say about the same as the towers.) So, Heiwa, in your mind, should Meteors just bounce when they hit the ground, and do no damage at all? That IS what you are implying, correct?

1st problem: weight is not the same as mass. Weight is not measured in kilograms, it is measured in Newtons. First week of high school physics.

In the physical sciences, weight is a measurement of the gravitational force acting on an object.[1] Near the surface of the Earth, the acceleration due to gravity is approximately constant; this means that an object's weight is roughly proportional to its mass.

In commerce and in many other applications, weight means the same as mass as that term is used in physics.[1][2] In modern scientific usage, however, weight and mass are fundamentally different quantities: mass is an intrinsic property of matter, whereas weight is a force that results from the action of gravity on matter: it measures how strongly gravity pulls on that matter.

However, the recognition of this difference is, historically, a relatively recent development and in many everyday situations the word "weight" continues to be used when "mass" is meant. For example, we say that an object "weighs one kilogram", even though the kilogram is a unit of mass.

Assume you are in the bathroom and step on the scale and that it announces that your weight it 120 kgs (or what ever that is in US - 20 inches)! OK, you are only 160 cms (what is that - 3 lbs?) tall, so you are a small, fat weight, but who cares.
2nd problem: Your units continue to be wrong. First, your weight is not 120 kgs, that is your mass. Second, you are equating kilograms to inches. One is a unit of mass, the other a unit of distance. Then you compare centimeters (a unit of distance) to pounds, (a unit of weight)

4th problem: Gross generalization.

Now jump on the scale!! WOSH, BANG!

What is your weight? Still 120 kgs! The scale records the same weight.
5th problem: The experimental evidence does not bear out this prediction. Have you tried it yourself? Obviously not.

6th problem: You are undergoing a rapid deceleration when you hit the scale. The more rapid the deceleration, the larger the force required to cause it. When the ground (or scale) puts that force on you, Newton's 3rd law says you return that same force to the ground (scale). That is why your weight changes.

You are falling victim to the classic blunder that is the bane of middle school students everywhere. Your weight certainly changes. It's your mass that remains constant.

7th problem: No, not normally. But you normally aren't falling onto your scale, either. But, in those instances when you are, your weight is more than it normally is, if only for a moment.

Okay, this convinces me more than ever that he's trying to pull off a dumb joke. No one can possibly be this benighted.

If this doesn't prove that Heiwa is here to simply be a mental sucubus...then nothing does. His/her mental state is seriously in question. The more you catar to it...the more you contribute to the problem.

My $.02.

My 220 pounds pinned my bathroom scale (which can hold 350) when I jumped on it from a standing start. NB: I have about an 18-inch vertical leap.

Let's stick to the subject.
Obviously, the H guy has not tried this himself...
Make it easy. Drop a 5 pound brick on the scale, after weighing it staticly.
That way you don't break stuff--or not badly...
