I have a very strong evidence .

That isn't evidence because I explained the flaws in your experiment. Go back and read reply 35.

Quote from: Yahya A.Sharif on 04/09/2020 21:23:07
So why do you ignore this?

I didn't. I pointed out why it is wrong.

Quote from: Yahya A.Sharif on 04/09/2020 21:23:07
No, If 15  kg raises 60 kg, there is a scientific explanation in which the idea 15 kg lifting 60 kg agrees with the law of conservation of energy.The idea is force vs force not work vs work .

You could use that to create net energy (I explained how), so conservation of energy is still violated.

The usage of energy as F*d  is wrong .Energy comes from a human being.

The source doesn't make any difference. Energy is energy.

I only need to demonstrate my great new discovery with its obvious observations,logical arguments and a true test
I'm sure no scientist will think he is carrying his body like carrying a rock or he is stupid.

It isn't.

There are none. Just misconceptions that you have.

Quote from: Yahya A.Sharif on 04/09/2020 22:59:33
logical arguments

Everything you've said is illogical.

Quote from: Yahya A.Sharif on 04/09/2020 22:59:33
and a true test

It's a flawed test. The fact that you can lift your own weight with your feet is proof enough that you are producing at least as much force as your own weight. The laws of physics demand it. The laws of physics don't change just because you don't properly understand them.

Quote from: Yahya A.Sharif on 04/09/2020 22:59:33

This is true only in the sense that the body is placed directly over the legs, whereas carrying a rock requires you to have it in front of you.

Just another thing of such a stupid scientist he will be happy that he flies jumping with a rock of 60 kg while this rock is hard for bodybuildings

Quote from: Kryptid on 29/08/2020 23:55:59
Then you are, as usual, ignoring the fact that lifting a 60 kilogram rock is equivalent to your legs lifting 120 kilograms total, because your body weight doesn't magically disappear just because you're holding something heavy. Of course it's harder to walk while carrying a 60 kilogram rock than it is to carry a 60 kilogram body because your legs are bearing twice the weight in the first scenario than they are in the second. You honestly can't tell me that you don't understand that.

60 Kg in a rucksack isn't nearly so much of a problem, because it's properly distributed, symmetrically, and with the load transmitted to the hips.
More or less like your bodyweight.
That's why it's easy to carry 60 Kg of bodyweight.
There is no need for any "magic".

That being said, I've lifted and carried around approximately 60 kilograms at my job on multiple occasions. I'm far from a body-builder.

Then you agree of what I say.You carry your 60 kg several times at your job while a bodybuilder can't , because you need small force to move your body than a body building uses to lift the same mass

The force is 34 kg for both legs , it will be 34 kg raising 57 .and I only used force far less than the maximum as in the video.
If what you say affects,  then the measuring can' happen because my leg will move to the right side.

What force?
The force you happen to exert is irrelevant since it isn't being use to hold you up.

Ahem:

Quote from: Kryptid on 29/08/2020 23:55:59
It only took 17 kilograms of force for you to full extend your foot under the restraint of that force gauge. That is not the same as saying that your foot can only exert 17 kilograms of force. You were unable to apply any more force to the gauge because your foot was already full extended.

Quote from: Yahya A.Sharif on 09/09/2020 15:19:28

Not if you're using other muscle groups to prevent your leg from moving.

By the way, I'm still waiting for you to prove that I can lift more weight than a bodybuilder, as you claimed that I could do so right here:

OK
Pressing the scale is equivalent to pressing the ground in lifting .I press the scale of maximum"17 kg one leg" and I left myself with far less than 34 kg"two legs" because I actually didn't exert that maximum effort as in the video

Your foot is on one end, but what is holding the other end of the scale?
