Most of my friends are like this, people who don't stay physically active usually do worse academically speaking/are less motivated.

OP is a faggot though, why don't you try to encourage people to be less "nerdy" rather than just breaking them down?
Also this popular idea of men going into science and engineering are nerdy/emasculated is only prominent in American culture. In my experience, most students in these programs are very well balanced.

Can you help me with this oh great engineer.

The ends of a water trough 6 feet long have the shape of isosceles triangles with equal sides of length 2 feet and the third side of length 2*sqrt(3) feet at the top of the trough, Find the force exerted by the water on one end of the trough if the tough is

a) full of water

I set up the integral like this


integral sign (62.5*(y)*(2sqrt(3)y)dy) from 0 to 1

my answer is 62.5*2*sqrt(3)/3 however the books answer is half of that. What did I do wrong?

1. I meant "community college" figuratively speaking. Your shit-tier university is no different from a community college. It has the same shit academics with piss-easy classes.

2. Everything from your actions points to the fact that you're in a no-name school. You think if you went to Stanford you wouldn't have said *something* about it when you boasted those grades? When you replied to my first post?

You know what you're attending, so you know it's a fact that you're in a laughable school.

3. Ok. Don't see your point though. Next semester *should* have tougher classes if you're doing things right. Still will be nothing compared to what a real school teaches.

4. Passed Calculus courses a while ago. Those are the courses that you would have failed, because you are an academic failure that cannot succeed at a real school in a real class.

because you didnt do it right. you can either take the height as the centroid of the trianglar cross section, or integrate a function of changing width. you chose the latter but did it wrong.

you're better off just finding the height of the centroid, call it h, and say P2-P1=density*gravity*h

if P1 is open to the environment call is 0atm in gauge pressure

so P2=P=density*gravity*h

P=F/A

So F=density*gravity*h*A

but make sure h is height of the centroid.

To tell someone to "solve without using calculus" doesn't even make sense. Calculus is just derived from combining several axioms, essentially the "rules of math' so you're saying to solve something using math without using math. It just doesn't really make sense in my mind, if you're given a math problem you should be allowed to solve it using anything

I think the problem OP was trying to get at is that everyone and their mother, no much how much of a failure they are, thinks they're the smartest person in the room.

When comparing individuals, you can immediately tell who's fitter, more financially/academically successful etc. -but you can't compare intelligence- because we don't have an absolute metric for measuring it. Every fucking mmorpg gamer, geek or weakling I've met always has the excuse "I have 145 IQ (from some shitty online test), I'm just not motivated to study, which is why I'm academically unsuccessful".
These fags actually think they're superior to others with regards to intelligence. They cling on to that one quality that they so strongly believe they have, but have never done anything with it, and their pretty arrogant about it too.

I respect genius-level math nerds who have proven themselves academically more than most people do, but these other fuckers need to be euthanized.

>> No.4188863

>>4188825

if you insist upon integrals...

you would need to correctly find a function of changing width related to height.

In general hydrostatic cases dP/dz = -rho*g

so we get integral dP = integral -rho*g*dz

dz is a differential height, and you'll need to change from dz to a changing width.

you'll need a function that relates width to height, and it's probably not a trivial function, and i don't really want to do it for you.

yes but integrating (2sqrt(3)y)dy) from 0 to 1 will give you the correct area for the cross section so I don't see anything wrong with my setup

intergral (Density*height*area)

intergral (62.5*y*(2sqrt(3)y)dy)

>>4188909

area of a triangle is 1/2 base * height, I don't know what else to tell you

>> No.4188925

>>4188919
integrate (2sqrt(3)y)dy from 0 to 1 and you will get sqrt(3)


now use the common triangle area formula base*height/2 which is 2sqrt(3)*1/2 which is sqrt(3)

Thus proving that intergral of (2sqrt(3)y)dy is the correct integral

>> No.4188929

>>4188909
you dont understand, its not all about the area you're integrating over, its really mostly about the orientation of the area.

if i take a triangle and dip it in water, and then rotate the triangle, the height of the centroid doesn't stay constant it changes.

you need to be more careful with your reasoning.
