dunno why i put L instead of M lol, stupid

i solved them all hours ago lol:

C----tractor wheel is inevitably going to spin in dirt with the trailer behind and the engine in front.
F----ballast on ship carrying load mean ship will be higher during a heavier load and sunk down at lighter loads.
N---This damn has more surface area. Assuming the ammount of water is the same for each structure is to assume the same force is going to be applied. Pressure=Force/Area. It is clear that the damn with the most surface area in this case is the triangle shape....
Q----and Q because rotation is more directed around the axis of the key whereas larger key handles provide for force that is less concentrated around the key shaft.......increasing the 'stifness' of the lock.

haha dont call people idiots when you dont understand how cargo ships work........look up the concept of ballast.....better yet....let me give my explanation ive had to give to 85% of the other miscers tonight.

aglhr

no idea about 2(g?) though

[demteddies]

yea, it is tricky:

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.

brah ur pretty far off with your reasoning on those... (like everyone else i thought it was the obvious, agmr anyway)

but as far as the answers given by OP-

C - Its not the larger wheels spinning faster to keep up with the small wheels...if anything the small wheels would spin faster to keep up with the larger wheels. But in this instance in a tractor the large wheels are the ones which drive the thing, and they spin around in the loose dirt without the tractor moving much. I think thats OP's reasoning.

F - yeh you're right

N - Nah, triangles are strong because they are essentially 2 compression struts with a tension tie holding them togeather. An arch will be loaded in compression but without the outward forces at its base so it doesnt require the tension tie. I still dont buy this one, i think its the arch.

B - No- a key with handle further from the shaft will turn with least effort. OP's reasoning is something about having a smaller handle means less chance of imbalance when turning and this makes it easier for a stiff lock....i dunno.

[milanooo]

Why the fuk are you kunts talking about loose dirt? Where in the question do you see anything about loose dirt.

You overanalyzing sh!ts.

C,

C--tractors driving wheel spins faster on loose dirt and mixes it up...no need to calculate diameter/positional velocity
f,--idea of ballast......heavier weight requires more ballast=more air in tank so the tank floats
N----the wall of N clearly provides more area for the water to push against....assuming the water is equal is to also assume the force applied by the water is equal.....only dictating factor is then Area...Force/area=pressure...the Greatter the area, the smaller the pressure exerted on the dam...the stronger the structure......just because hoover dam is a curved arch doesnt mean anything..that dam is a particular type where the gradient slope of the dam gradually pushes on the water because gravity is literally pushing the dam back at the water....its a tricky questin.
q---stiff lock implies non-perpendicular rotation to axis of key-shaft will cause a "stiffness" or lockup to be felt......
therefore, the more central you can get the rotation, the the smoother the key will turn.

N - Dam having more surface area means stronger? no mate its not that simple. The triangular members are loaded along their length and will be subject to bending, which means tension on their outside faces. This makes them weak (assuming concrete or something). The arch will act purely in compression and is much stronger. As a quick sanity check why do you think dams are built arch shaped and not triangular?

Im a civil engineer and design dams, etc for a living.

explanation for answer F on the cargo ship

1. CARGO ships are huge ships that have ballasts inside of them. A normal ship carrying an insane amount of weight would simply get pushed down and sink into the water. Ballast tanks allow for either AIR or Water to occupy the space.........when air occupies the space, the bouyancy increases and more weight can be held(this great effect can be seen when you try to push a beach ball under the water) , however, when the ship is empty(or less cargo) air in the ballasts would mean the ship would be extremely 'tippy' because of all the bouyancy(this is simlar to a beach ball above the water(you notice how easy it rocks up and down and jiggles with the water)). This can cause the ship to tip over. So to counter this, they allow water into the ballast tanks to add stability to the ship.........this would be like filling a beach ball with water and then having it sit in the water......it will sink a little bit and be more stable..........


this cargo ship had too much air in its ballasts and not enough 'cargo'



it simply tipped over..if more water was in its ballasts, the water would have stabilized the ship by pulling it down.

[Sergis]

i like how tractors always slip on dirt and how a larger buoyancy force completely nullifies the weight of the load. on the misc you learn something new every day.

No, (and first off you are refering to torque), but torque will only add to the stiffness of the key........you want ideal key to have the most direct rotation applicable, (that is, a tighter limit of rotation)....say the key handle was 3 feet long(just to make a point), if you unevenly apply pressure to this huge pivot, the key will "stick" that is, it won't turn smooth.................the smaller you make the axis of rotation, the less chance of uneven application of torque(that is, the key will turn more smoothly) think of it as rolling a needle between your fingers......that produces a nice, tight, uniform rotation that is ideal.

[jwlee7ucla]

it's not A b/c of the diameter as i said, RPM will be different, speed won't. and the keys are different b/c of the length of the part you grip. greater leverage = easier to turn. think of it as using an allen wrench. it's way easier to turn if you insert the short part and have the whole long section to twist than the other way around.

"which spins faster" = rpm = A

1: All equal

2: G.

3: M.

4: R.

How to check answers?

haha it has nothing to do with torque dude........nothing at all.......why do you need torque to turn a key........the question is about finding an object that will minimize fluctuations in smoothness in the turn.....that means you want a small area....think of rolling a needle between your fingers.....that is a tight rotation......now take that same needle and stick it through a 2X4 plank..........try getting a tight rotation of the needle by manipulating the sides of the plank......it would be really rough and 'sticky'

Doubt you figured it all out on your own before OP posted the results.

[jwlee7ucla]

I swear all the non-agmr people are retarded.

A- There is nothing that talks about dirt, so theres there "slippage"- Does it say "when tractor is driving in dirt?" No? Then that means it could be driving on asphalt on the way to dirt, and a tractor won't go fast enough to "slip" on ground will it? In this case fastest spin = rotational speed, and smallest diameter wheel will spin faster to go at the same mpg as a big wheel.

G- It says IDENTICAL SHIPS- that means the ballasts are identical too. You are playing on the fact that the only differeng item between all three ships is the load. If one ships ballast is filled and another is not, then its not IDENTICAL anymore is it? On top of that, if you want to assume that ballasts ARE adjustable in this scenario- since you have no given amount of weight, you can assume any possible weight of cargo on each of these three ships- and with the changing ballast-to ship ratio, ALL THREE SHIPS WILL SINK THE SAME DEPTH. no?

M- arches- 'nuff said.

R- all keys are identical, and the shaft are of identical length. The only thing thats different is the size of the turn handle- which means you look for leverage in your answer. longer the turnkey the easier it turns in a STIFF LOCK.

[Sergis]

do you not understand how cargo ships work dude.....i explained it above............read the post above with the ship tipped over in the water and try to understand the concept of ballast.......if you can't understand that then gtfo

how about you try to understand the concept of the weight still pushing the ship down, ballast or no ballast

F ship is fuking empty and should be tipping over just like in your pic

[FeelTheFear]

1). D because it is nearest the engine so it would turn slightly before the other wheels (although now that I think of it, C and D would be equal because of the drive shaft)

2). I said can't tell because... don't really even know wtf it's asking

3). M because it's bending towards the water

4). R because leverage
