If superpowers were real: Super strength - Joy Lin

Kada bi supermoći bile stvarne: nadljudska snaga - Džoj Lin (Joy Lin)

Prevodilac: Mile Živković Lektor: Anja Saric

If you wake up one morning

Kada biste se jednog jutra probudili

with 1,000 times the strength you had the night before,

sa snagom 1000 puta većom nego prethodne noći,

how will you handle delicate day-to-day tasks?

kako biste se snalazili sa delikatnim svakodnevnim radnjama?

Everything must seem so fragile to you

Mora da vam se sve čini krhkim

since the scale of your strength

pošto se vaša snaga uvećala

has expanded one thousand times.

za hiljadu puta.

Morali biste da budete veoma pažljivi

You'd have to be very careful

when you're shaking someone's hand

kada se s nekim rukujete

so you don't end up breaking their bones

kako im ne biste polomili sve kosti

or crushing everyone you hug.

ili smrvili svakog koga zagrlite.

And using a fork to pick up a piece of broccoli

Nabadanje komada brokolija viljuškom

from a Styrofoam plate

sa plastičnog tanjira

without driving the fork through the plate

a da ne probijete tanjir viljuškom

is going to be as difficult as brain surgery.

biće komplikovano kao operacija na mozgu.

Recimo da taj dan dođe

Say the day comes

and you get the chance to save a damsel in distress

i imate priliku da spasite damu u nevolji

falling from a helicopter.

koja pada iz helikoptera.

Tako ispružite svoje ruke

So, you hold out your arms,

hoping to catch her.

nadajući se da ćete je uhvatiti.

Seconds later, you will find yourself

Nakon nekoliko sekundi, zatičete sebe

holding her lifeless body.

kako držite njeno beživotno telo.

What happened?

Šta se desilo?

Well, pressure is force divided by area.

Pa, pritisak je sila podeljena sa površinom.

The smaller the area,

Što je manja površina,

the bigger the pressure.

to je veći pritisak.

This is why we can lift heavy objects

Zato možemo da podižemo teške predmete

without breaking our skin,

a da ne probijemo kožu,

but a tiny needle can make us bleed

ali zbog malene igle prokrvarimo

with just a little poke.

uz samo mali ubod.

The pressure that will be exerted on her body

Pritisak koji će biti ispoljen na njeno telo

može se izračunati tako što se sila

can be calculated by force

divided by the area on the top of your arms

podeli sa površinom na vrhu vaših ruku

that comes in contact with her.

koja dolazi u kontakt s njom.

It doesn't matter if your arms are strong enough

Nije bitno da li su vam ruke dovoljno jake

to catch her body without breaking your bones.

da uhvate njeno telo, a da vam se kosti ne polome.

Her spine is not strong enough

Njena kičma nije dovoljno jaka

to be caught by you without being damaged.

da je vi uhvatite a ne oštetite.

Even if you rip off the nearest door

Čak i kada biste otkinuli najbliža vrata

to provide a bigger area to catch her with,

da pružite veću površinu s kojom biste je uhvatili,

you still wouldn't be able to save her anyway.

svejedno ne biste mogli da je spasite.

Remember, it's not the fall that kills her,

Zapamtite, ne ubija je pad,

but the sudden stop at the bottom.

već naglo zaustavljanje na kraju.

Let's say she's falling from a 32 story building,

Recimo da padne sa zgrade od 32 sprata,

about 300 feet,

oko 90 metara,

and you are 6 feet tall,

a visoki ste 180cm,

maybe 10 feet on your tippy-toes,

možda 3 metra kada se ispružite

with your arms above your head

s rukama iznad glave

holding a door,

koje drže vrata,

in hopes of distributing the pressure

nadajući se da ćete rasporediti pritisak

across a larger surface area,

preko veće površine

but all you're doing is essentially moving

ali vi zapravo samo pomerate

the ground up by 10 feet.

tlo za 3 metra.

So, she's now falling from 290 feet,

Dakle, ona sada pada 87

instead of 300 feet,

umesto 90 metara

reaching the speed of 173 feet per second

i dostiže brzinu od 53 metra u sekundi

just before impact,

pred sami udarac,

not counting air resistance.

ne računajući otpor vazduha.

It's the equivalent of crashing at 94 miles per hour

To je jednako sudaru pri 150 kilometara na čas,

into a wall with a door in front of it.

u zid koji ispred sebe ima vrata.

The only thing that could save her is flying.

Jedina stvar koja može da je spasi je letenje.

But that power comes with its own host of scientific issues.

Ali ta moć dolazi sa sopstvenom hrpom naučnih problema.

If you could fly,

Kada biste mogli da letite,

morate da doletite do nje,

what you must do is fly up to her,

start flying down at the speed she is falling,

počnete da letite brzinom kojom ona pada,

hold on to her,

uhvatite je,

then gradually slow down

onda postepeno usporite

until you come to a complete stop.

dok se potpuno ne zaustavite.

This process requires a lot of cushion space

Ovaj proces zahteva dosta slobodnog prostora

between the point she starts falling and the ground.

između tačke kada počne da pada i udarca o tlo.

Every second you waste

Svaki sekund koji protraćite

on changing into your superhero costume

presvačeći se u svoj kostim superheroja

and flying up to her height,

i leteći do njene visine,

her head is getting that much closer to the pavement!

njena glava je sve bliža udarcu o beton!

If she's falling from a high place,

Ako pada sa visokog mesta

and you can't get to her

i ne možete doći do nje

until she's only a few feet above the ground,

dok nije samo nekoliko metara pred tlom,

there's really nothing you can do

ne postoji ništa što možete da uradite

other than magically turn the pavement

osim da beton magično pretvorite

into marshmellow

u beli slez kako bi ona

to allow her enough time to slowly come to a stop.

imala dovoljno vremena da se polako zaustavi.

Then, break out the chocolate and graham crackers

Onda izvadite čokoladu i krekere

and you've got s'mores.

i imate poslasticu.

Mmmm, delicious!

Mmm, ukusno!

Now, which superpower physics lesson

let,

super strength,

nadljudska snaga,

immortality,

besmrtnost

and
