Is it true that a 45lb plate weighs more than 4 10 pound plates + a 5 pound plate?

This is why you should lift with standard weights. The hole is smaller so you get more weight per pound. A 25lb standard plate is worth 2 45lb Olympic plates

This picture is wrong in so many ways...

I think you guys are memeing but now I gotta check my weights

can someone explain this?

o no

It's not rocket science bruh
>2 pulley
>you lift 100kg + 5kg roller
>3 pulley
>you lift 100kg + 2 x 5kg rollers + 10kg bar

Yes because the hole is the same size

the pulleys weigh 5kg and the bar thing connecting the two bottom pulleys weighs 10kg, its fairly obvious if you aren't ratarded

so the first pic is troll?

More pulleys there are, the less effort you need.
Direct any further questions to Archimedes, he knows all about pulleys

yes, you can't just magically lift weight with pulleys and shit

>Archimedes
sounds like a fag

>and i thought the whole brainlet thing was a meme

did you retards fail high school physics? it takes less force to pull the same weight bc you have to pull further

2nd pic is a troll, my dude. Seriously, take the other user's advice and look up Archimedes

who are you talking to? are you insane?

i just read about it and its like black magic to me

Come on man, don't ruin the fun.

truth

Does the pulley in the first one not weigh anything?

i don't understand that comic

>not using milk cartons with sand
>not using buckets of your own cum
>not curling grocery bags with milk
>not bench pressing the earth with each pushup

Plebs will never make it.

Compound mechanical advantages, use them all the time at work. Each traveling pulley will cut the weight of the load in half but you’ll only raise the load at half the rate. Using one traveling pulley for every 1’ of cable pulled you’ll only lift the load 6” but can lift twice as much.

i didn't get it at first either, but i think i got it after reading it a couple times.
>asian man needs to get some bread (probably to use in some kind of meal for his family)(we can assume that the asian by in the first panel is his son because they look alike, and it is unlikely there are many other random asian children around because the sign for the grocery store is in english) (and even if there were, why would this man be telling an unrelated asian about his needs?)

This

It’s a profound allegorical statement on the nature of human existence. The man’s proclamation “I need to get some bread” is the cry of every man alive. What is bread? Food. It’s a powerful statement indeed. “I need to get some bread”. “I need to get some bread”. You can feel the weight of it, “I am here and nothing can stop me”. “My life has value”. It is the resilience of the human spirit and the drive to survive.

You can’t overlook the second panel, though. The cashier states that the bread costs $1.15. The register confirms this to be true. So the second panel is highlighting the importance of truth and virtue in society. The bread is therefore an allegory for truth as well as food. For truth is the bread of a healthy civilization.

Hey genius fuck tards, if pulling shit around a circle basically makes shit half as heavy, why wouldn't we just get a trillion pullies and pull backwards against the Earth's spin and stop the rotation so that it's always daylight?

This is a neutral comment. I'm here to tell truths.

In principle, it would all weigh the same. The truth is that there's quite a bit of weight variance between the makers of plates, and more plates means more chances for degradation over time.

Despite what other posters may have said, this image is actually quite true. Adding a pulley reduces the overall force needed to move a weight, but increases the amount of rope pulled. This principle allows cranes to operate.

Because the sun hurts my eyes

one time I tried benching with just 2.5's on each side (dont ask me why) and it felt way lighter then just the bar so this actually might have some truth to it

Who counts the bar?

Trolling aside, you also have to factor in the weight of the added equipment too.
And yes, you will require less force to pull it (it will be easier to lift), but you'll have to pull it LONGER to reach the same height (which means more energy is needed overall).

How to trigger any engineering student in a single picture

I unironically filled 5l bottles with water and curled that shit back in school. That's how my interest in working out was born.

If rocket fuel is used to propel shit really fast, why don't we just make better rocket fuel to make faster shit?

>attach a pulley to the earth
>it immediately loses half of its weight
