lol the classic hat question.
if it wasn't because of that question I would have never passed MATH302

AGMR did not have to look more than a glance.

agmr

all of em are pretty easy except this one.. Test 24

or im just bad with numbers

Yeah, I misread the question. Didn't see the "identical"
I don't think the logic behind this question is supposed to be so complicated
with ballast tanks being involved. So I would have picked "G" then.

:lol I messed up the first question. My first response was "C"
cause I thought big wheel means faster rotation (on the outside)

For anyone that disputes the dam question.

Hoover. End of Story. It's concave towards the water for a reason. Arches are the strongest form, put the strong part towards the pressure=win.

leverage? easier to turn? that was my assumption.

I think you mean convex towards the water. Concave would be worse than a straight dam.

agmr

there's a reason why most dams are built like that

it's shaped like that so most of the force is spilled towards the land mass and not perpendicular to any section of the dam (minus the exact midpoint of course)
lower dams can be built as a "straight line" simple because of the lack of vertical pressure.

i just looked at other RS members so



:ilied:

i only got 2/4 right haha
i was staring at the boat one for a while...didn't read the word identical because i was pressured to finish it in 15 seconds.

was also staring at the dam one for a long time...didn't know which angle i was looking at the damn thing :fail:

Strong thread copy from misc.

and supposedly the real answer is not AGMR, hold up.

here u go:
c: this ones easy. larger wheels (higher radius) need to turn/spin faster to keep up with the smaller radius ones. simple angular velocity problem.
f: all the ships are the same, except some are more submerged than others. the one that is submerged the least has the highest load since it needs the largest buoyancy force to keep it afloat so high.
n: triangles. they have unique properties (some type of geometric properties, i forget exactly) that make it very difficult for the water to break it.
q: since the key with the smaller handle is closer to the rotating shaft, it will require less effort - pretty simple.

theres actually a lot of solid arguments on different variations of answers also

Fack im an idiot
