Another physics question from the Mod team today. (we're in class, srs)

[Final_Rep]

My prof asked, "What would be harder to bench press, assuming the weight was balanced? 350lbs of lead or 350lbs of feathers?"

Obv. I immediately spoke up and answered him correctly, but what did I say?

Please also see this thread for a more advanced question:

feathers because of the uneven weight distribution

[MontavonM]

350 = 350

[aaron501]

lead, since the feathers density is lower so they would be massive ****ing bags of feathers causing leverage to come into effectiveness.

[OVOTexasBrah]

Same 350 lbs= 350 lbs

[Mcfreako]

Neither because mods don't lift

[TDKSparda]

lead because feathers have holes in them

[Kurial]

are we assuming same atmospheric pressure in both systems? or better yet, are we bench pressing inside a vacuum?

[Bigdumogre]

That you can't lift 350lbs of anything?

[emperordeadlift]

why do you keep banning me? let's just be friends, ok?

[havoc713]

350 pounds of feathers. That quantity would be so large, it could probably reach the ceiling. If the feathers are already hitting the ceiling, you might not be able to bench it the whole way up. Doesn't matter if they weighed the same, the feather take up more room. Hence the difficulty.

How can we bench if our arms aren't real?

But, err, I mean... wait, how do... what's the ahhh... damnit.

are we assuming same atmospheric pressure in both systems? or better yet, are we bench pressing inside a vacuum?

Of course this is done in a vacuum, to isolate the variables properly.

[astonmart]

depends how much the bar weighs and wind direction that day (feathers blow in wind lead does not ( i think) )

memcop wins this round... /thread
