Imagine wheel A with diameter d, and wheel B with diameter 2d.
To go a distance of d, wheel A turns once, whereas B only makes a half turn. Therefore, wheel A is turning faster than wheel B!
You're applying angular velocity to the wrong problem.

But if they are all moving at the same time, like a truck with one big wheel and one small wheel moving at 1km an hour, won't they be moving at the same speed? It's not saying which one goes around faster, just which one moves faster.
I don't know, I don't remember much from physics class.

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 | Are you in or ed? |

The question's just asking which key would be the easiest to turn

heres my understanding of the questions
1) a, smallest wheel = smallest circumference, if comparing to C, the circumference is far greater than a, so to a set variable of distance, a would have to turn faster in order to cover the set distance compared to C and other options
2) the key term is identical ships, and the only variable is load. thus all else equal, the one that sits the lowest on the water line = the one is closer to displacing the same amount of water that it occupies. if the load/mass is equal to the displacement of water from the ship, ratio 1:1, then neutral buoyancy is achieved thus, lowest in water is G, because stated in the question is "identical ships".
3) here is an easy experiment, you push ur arms on the side of an entry way, with someone applying force behind you. its much easier to hold that force back than if you were pulling with ur arms from the entry arch way. in essence, this basically an arch. instead of pressure and force of the water it is holding back, think gravity.
4) turning requires TORQUE, torque = force x distance. distance from the center of the key to the outer edge of the handle more distance assuming you have a set amount of force = more torque. example, think of a screw driver, whats easier to turn or loosen a stuck screw, a dinky little screw driver, or one with a huge ass handle? or a standard 6in ratchet over a 2ft breaker bar.

| 1. all 4 wheels " turn " at the same rate since they're on the same vehicle, it's not asking for which wheel makes the most " rotations ", hence they're all equal
2. you're not taking into account the buoyancy and the ballasts. ever wonder why cargo ships with a lot of cargo still sit relatively "high" in the water? It's because they increase their buoyancy with air in their ballasts.
3. You didn't take into account the slope/gradient.

LOL everybody's over-analyzing the questions; just assume that there are no factors involved
it's a simple 1-minute test that exercises your ability to judge
it's not like you'd be able to do all those calculations in the allotted time anyways lol
I still believe in AGMR |

fair enough, but if your arguement was true for #1, then i would never see a customer come in complaining about the abs light, tmps trigger on, and customers complaining how their speedo is now out of sink with their gps speed due to aftermarket wheels with oversized or undersized tires. overall diameter is greater on the wheel = greater circumference. cars abs/wheel speed sensor is now calculating the difference, so it thinks the car has a flat, hence trigger the tpms error to turn on.
2, wont argue with you on that, as i didnt take into account ballasts inflated air, so yes, i will actually agree with you on this one.
3, there is only so much information provided from a 2 dimensional drawing. nor was their a structural integrity test and examination over the structure. either way, it should still be strong to house megatron if the time is needed. Quote:

The thing about over-analyzing is that the questions themselves were poorly made.
There are many things that depend on them. The answer for 4 for example, if one make absolute 0 assumption on how the key is being turned (the point where the force is applied, how is it applied... etc) , none of them are correct answer.

Since people STILL aren't getting the first one, I made this to help you visualize:
Now picture the tractor moving, and all wheels spinning. How many times do you think the white line reaches that position on the small wheel before it does on the largest wheel?
Now remember, the line goes all the way to the hub.
So the smaller a wheel is, the faster it turns.

^ but the axles rotate the same since they're from the same vehicle, so essentially they "turn" at the same rate. this isn't in regards to the total # of "rotations" it makes. they all equally " turn " at the same rate.

The axles with the smaller wheels on them will turn faster
If you still don't get it after that visualization then I don't know what to say

they dont turn at the same rate b/c the smaller one needs to turn faster to make up for the distance b/c its smaller. so to keep the tractor going at 10 km/h the smaller one needs to turn faster

if your argument is true, then having 2 tires of completely different sizes will not affect vehicle speed?
there would be no point in transmissions, and gear ratio's as they would all rotate at the same speed no matter what size they are.
think of it this way, a large dog strides along easily during a walk, while a small little dog has to frantically run faster to keep at the same pace, why? because for every large step of the long legs of the larger breed dog, requires the itty bitty dog to take 10 small steps. the rotation of the longer leg, allows for a longer circumference thus, a longer stride.

Looks like the answer to thread subject "How smart is REVSCENE" is one of the following:
a) not very smart
b) too smart for itself
