>>42673323
Depends, where's it being held?

>>42673323

Need the exact distances from each plate to the centre of the bar, but I would guess it would tip on the green side since they are further from the centre.

>>42673356
that's just the equation for torque. you'll learn it in any physics class. good luck with ur studies

>>42673356

Alternatively, buy a school textbook at your level and watch some youtube videos on the topics

>>42673323
Blue because torque.

τ = r*F*sinθ
The torque on the right side would be greater because of the increased displacement of the green weights when held from the center of the bar. Since the torques from the blue and green weights are in opposite directions, when held at the physical center of the bar, it would generally rotate on the side of the green. If held at the center of mass, though, the bar would not rotate.

Assuming all the plates are of equal SIZE 1m width

So the middle of the blue plates is 1.5m away from middle of bar, middle of green plates 3m away from bar.

M = 1.5*60-3*60 = -90

So it will tip right

>>42673331
It will tip toward blue. There is more weight further away from the pivot.

exactly the opposite.

friendly reminder to always use even pl8s on both sides to prevent memesters walking up to you pretending to educate yourself

>>42673323
This is literally introductory physics, a basic conceptual torque question. Assuming it's held at the center of the bar, it tips to the blue because the blue is farther out.

>>42673323
the 20kg side duh

20kg>10kg

This is a bad illustration, because with this example the bar would tip to the blue side, because of the further distant, of the blue side.. But in real life, there will be an equal distant, between the middle, and each sides, which will make it tip to the green side

>>42673460

The picture doesn't accurately represent a barbell.
You can't put plates further on the bar on one side compared to the other.
The center of the barbell is directly center of the first plate on each side.

So unless you hold the bar closer to the green side, it will tip on green

Too bad in reality weights slide all the way in. There'd be more weight acting on the lever with more smaller plates. Big plates would be closer to the center


For your illustration you are correct though. Because somehow we've put clips both on the inside and outside of our Weights to keep them in that awkward position

>>42673642
if you're a real men it wouldn't tip because real men, unlike you, have enough strength to still hold it in balance.

>>42673833
In that case it will tip towards the bigger number of plates. Its not like the plates are infinitely thin discs.

>>42676243

Holding the bar in the center of your retarded and coping version with the blue plates at the end of the bar, which would cause the center of mass to move closer to the green plates, approximately where I marked the center of the bar in the second drawing (impossible to tell without measurements), will not cause the bar to tip.

You're not actually refuting my points at all.

>>42676713
No, there's nothing there supporting your twisted idea expressed in >>42676406 about the relevance of the center of the bar. Quite the contrary. The "center of the bar" is wrong in both approaches. The more the number of small plates on the right, the more evident.

>>42676686
Please tell me where you think the center of mass is when the plates are equal distance from the center of the bar and when the plates are equal distance from the end of the bar.

>>42676773
Look at the png. "Equal distance from the center" means jack shit.

>>42676772
How is the center of the bar wrong in that picture?
I did say approximate.

And I need to state where the center is because the center of gravity will shift depending on the scenario.
In >>42676618 , same as my first picture, the center of gravity would not be the center of the bar.

Still not refuting and stating your points

>>42676793
Where the center of the bar is determines how far the center of gravity shifts.
In your retarded scenario of plates at the ends, center of gravity shifts more than the center of gravity would be if the plates are equal distance from center of the bar.

>>42676871
Last try.
>>42676618 clearly shows where the theoretical center of the bar would be if the plates are at the end (red) and if theyre loaded on the bar normally (pink)

>>42676906
Sure, and the theoretical center of the bar is IRRELEVANT in both cases.

>>42676920
The center of the bar is relevant because, stated in my very first post in this thread, holding it at the center would cause the bar to tip toward green.
However holding the bar closer to the green plates, more accurately represented in >>42676618 than in my picture, would not cause the bar to tip.

Depends on grip.

>>42676966
>The center of the bar is relevant because, stated in my very first post in this thread, holding it at the center would cause the bar to tip toward green.
Therefore, it's IRRELEVANT.
>>42676966
>However holding the bar closer to the green plates, more accurately represented in >>42676618(You) than in my picture, would not cause the bar to tip.
"Closer to the green plates" is not "centre of bar".
"Centre of the bar" is not the barycentre.
Therefore, the centre of bar is again IRRELEVANT. It's just the wrong concept to adopt here. We're looking for the barycentre, not for the centre of the bar. The centre of the bar won't be the barycentre if the barycentres of the weights on the sides aren't equally distant from the centre of the bar. In this case, the barycentres of the weights on the sides are not equally distant from the centre of bar (no matter if we decide to opt for a bar of this length >>42673642 or of this length >>42676618 ) and it will be even more twisted if we used smaller plates on one side or bigger on the other side.
The. Centre. Is. IRRELEVANT. It's a mirror for larks and faggots.

>>42677077
I never said barycenter.
When I said "center of the bar" I mean equal distance from each end of the bar, i.e center of the bar to people who aren't braindead.

The only reason I would talk about the center of the bar is to show that where the point of vertical force is what determines if the bar tips or not.
Please, for the love of everything holy, understand this. At this point I'm trying to help you.

We can't neglect the bar's weight. If you have to change the laws of physics to prove your point, you're probably wrong.

Exerting vertical force on the bar on the center of the bar, i.e. deadlifting normally, would cause the bar to tip.
This is because where the point of force is on the bar is what matters, i.e. center of gravity or yellow line in >>42676618

Since the bar is going to be held by two arms, the pivot is always in the center for that specific axis.

The blue plates are on the tail end of the bar though in the diagram, so if the bearings were visible on the diagram you'd see the center of the bar itself is closer to the green plates.

The bar would tip towards the blues as not only does it have more weight, it has more weight further away and concentrated on the further weights due to their more compact size.

>>42675507

There's obviously an ambiguity hence the meme argument

Assumption 1: the blue plates are on the end of the barbell as depicted

vs.

Assumption 2: Bar not drawn to scale. Plates are mounted at the collars on a symmetrical barbell.

Whichever assumption you make determines the answer.

Depends where the fulcrum is.

don't you have to factor in the rotation of the earth when working with big weights? like the auroria borealis effect or something? it was in cod4

Only on 4chan and facebook does this kind of post start an argument.

ITT retards that can't do math. The plates are different weights but each side weighs the same, so it wouldn't tip

Congratulations, retard.

Look, another idiot.

I bet that in this case >>42684095 you really believe that if you lift from the middle of the barbell, the barbell won't tip. Yeah, you're retarded.

>that uneven line
I'm sorry but it triggered my autism

It wouldn't tip at all. There is no ground, gravity or force applied to it.

Blue side has greater momentum so it tips towards it

>>42673323
This makes me so fucking mad
>the question isn't clear
>the image doesn't give any data or information about whether the bar is in the air, where is the centre
>if the question were clear it could easily be solved by a high school student
Kill yourself faggot

Moment

Blue tips down, it has a longer lever arm and thus has a higher torque

>>42673356
Have you seen Billy Madison? That should give you some ideas.

>>42680752
You are a fucking idiot. You have three 20s which have the same distance as the 3 final 10s but have double the weight. Therefore the 3 10s closer and have the same weight . They had to have the same moment to balance. They don't so blue wins

IT'S NOT TORQUE IT'S MOMENT

>>42673323
That depends on where you grab it desu.
