Heiwa's bathroom scale experiment

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.
 
Umm...i weight about 165 and it jumps to 200 and higher when i land on the scale from 1 inch higher.

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!

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... ;)



ETA: Curses, dtugg beat me to it.
 
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?

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.

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.

wikipedia said:
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.

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.

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)

3rd problem: Gross (heh, heh!) generalization.


Heiwa said:
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.

4th problem: Gross generalization.


Heiwa said:
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.

5th problem: The experimental evidence does not bear out this prediction. Have you tried it yourself? Obviously not.




Heiwa said:
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?
Click to expand...

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.



Heiwa said:
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.

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.
