Not only you know the solution when you're white, you also see people arguing when they're not even if their skin color says otherwise. It should be standard test at border points and prerequisite for citizenship.

>>539608710depends on your cuntfor example i am currently about 5-10 meters to the nearest pole
>>539608710That's one of those "are you paying attention or just following formulas?" kinds of questions. Hardly a whiteness test but may be better as an NPC test.

>>539609006Bold of you to assume it's to scale.

>>539608710you're missing informationthe cable is 80 m longbut how many meters is it short?
>>539608710113m innit?
>>539608710I'm not white so I don't know the answer
>>539609197Nah, the diagram is fucking with you.The cable is 80m. It drops 40m (50 - 10). Ergo the distance is x = 0m as it goes straight down and back up for a total of 80m.
>>539609099Why should be the scale and proportion be wrong and not the text "Cable is 80 m long"? I rather trust the forms that i see and not the text.
>>539608710zero, no?from pole A to pole Bpole A top, the cable has to drop 40 metres down, AKA 10 metres above ground, then it has to go another 40 metres up to reach the top of the pole B
>>539609438And this is why mathematics beyond basic daily computations is absolute bullshit. Let's make it as abstract and subjective as possible.You tell me numbers don't lie yet you can't find the final digit of Pi.
>>539609438Does that actually hold true given that the cable isn't taut?
>>539608710This is impossible. The cable is drooping 40 meters below the straight line. It has to be 112 meters long. And the poles are 80 meters apart. Trick question?
>>539609476They don't do that "not to scale" bullshit in Germany?However, in general, you should assume the description is accurate and the drawing is a visual guide unless it is explicitly noted as "being to scale".
>>539608710About an inch and a half. I used a ruler.
>>539608770This...OP is a 1pbtid faggot/thread
>>539608710I don't have a need to memorize catenary equations.>41.89 m
>>539608710It's 2*sqrt(50)
>>539609614If the cable was taut then the distance x would be 80m. In fact, that is the upper possible bound as the cable is noted to be 80m. However, it is very slack therefore the distance between poles A and B must be <80. The rope drops 40m at some point (assumed to be mid-point). Thus the distance between A and B must be 0m as the whole length of the rope is used reaching the 10m point from the top of A and going back up to the top of pole B.
>>53960871040M
>>539608710Easy:>that's not how geometry works
the poles are as far apart as a fab blast throws them
>>539610201Its 16m you idiot.T. Me to myself.
Generally for a wire you'd use the wave equation right? >https://en.wikipedia.org/wiki/Wave_equationBut unless I'm mistaken that only works for a wire under high tension, which this wire is not. So you'd have to go do some fundamentals and break out your force diagrams and prove what shape it hangs at for a slack wire. You might assume a parabola, but I would actually surmise it's something between a parabola and a triangle, and it would depend on the elasticity of the wire. higher elasticity is more of a parabola. One factor is, the tension in the wire is not evenly distributed. It's hire near the support pole which is holding up the weight of the wire in the center. Normally tension is evenly distributed, but that's for a wire pulled taught. It still might be the case, it's just something to consider. Anyway, once you find the shape, you just do the old calculus trick to find the length of the wire for dxintegral (dx^2 dy^2)^1/2 = integral (1 + dy/dx^2)^1/2 dxThis integral is likely super messy but solvable using tricky trig substitutions. Now you have an integral for length with respect to x. Should be able to solve backward for x.
50 - 10 = 4080 / 2 = 40180-90 = 90both sides are the same length and it's a right angle triangle 40/cos45 = 56.6mI think anyway
>>539610063Well shit take my white card, I assumed too much thinking it was a catenary. The only way 80m of cable can go from 50m to 10m and back is by straight down and up, meaning zero distance between the poles.
>>539610616Nah its 16 because 80/5 = 16
White people have been convinced into wasting their lives solving inane trash instead of breeding
>>539608710Its basic fucking calculus but nobody here got past primary school before being raped and thus learned nothing
>>539610153>trusting the diagramsheeple
>>539610153Damn, that makes sense actually.
>>539610153You misunderstood. I meant taut being pulled down to 10m.
>>539610942The diagram looks like an envelope :)
>>539610719Yes maybe because its not fucking useful in real life unless you are a researcher or phyiscist.
>>539608770Yes. Since the rope is suspended 40 meters in the air and both halves are 40 meters long each. This means that the rope would hang straight down without any gap between the poles.
>>539611009It's M shaped for masons
>>539608710kfc^3
>>539611101You've got a point, so it's 0m
>>539609594>you can't find the final digit of PiHold my beer
>>539608710>0m distanceOP just likes touching poles
>>5396087100m. Nigger.
>>539611258You win Internet if you can. Do it in this thread, anon.
Gay Poles.
>>539611121M for Monero BUY BUY BUY BUY
>>539610616Actually I realise my mistake I've been treating it like a right angle triangle but this is about the horizontal distance apart.It's zero,The lowest point the cable touches is 10m off the ground at the midpoint, the mid point of 80 is 40. The poles are actually touching and the picture is misleading.Fuck you OP
>>53960871080m
>>539608710These threads are pointless, a substantial amount of people run shit through AI now and then answer as if they didn’t.
>>539610616Can you even use sin/cos here? A cable tied to two poles doesn't fall into a half-circle does it?
Engineer here. I consulted the catenary equation, and determined the length to be zero. One weird trick project managers hate.
>>539612507Catenaries use hyperbolic trig functions, but this is a trick question.
>>539608710You can use hyperbolic cosine to do this.
>>539609438damn, you're right. i'll down a schnaps in shame, hoping to be able to cope another day. i did not spot it. mufagginmuffafah. darn kikes and their trick questions. fekkin bloody. my technostream plays a PIL remix 'open right up'. i'm old.
