Puzzle! (dont ruin if heard it before). Are you clever?curtybirdychopper
Dec 4, 2002 2:31 PM
A cyclist stands outside of a bike shed that has one door and no windows. Inside the bike shed is a single light. Outside the shed by the door are three light switches. The cyclist is challenged to figure out which of the three switches turns on the light bulb inside the shed, but he has only one chance to open the door to find out if he flipped the correct switch. What should the cyclist do? If he fails, he will never be able to get with the hot podium chick and will forever be banished to ride alone on a 50lb k-mart special up 15% grades with flat tires in cutoff jeans behind a caravan of Ford Excursions.

I don't know, man!

If he flips them all, he wont know which one in particular works. C'mon, man, how would you like wearing jean short cutoffs while riding.

Is there a rule that he cannot prop the door open and flip the switches? He will have only opened the door once.

That's what I'd do.

once he opens the door, he can do no more flipping.
unfair!Qubeley

You didn't say that in the original question!
Let me try it one more time:
The bike shed is so poorly maintained, there are holes on the wall that you can see through.
Let me guess..Qubeley

Open the door, leave it open. Then try out the switches?
I hope he can climb up the podium with the hot chicks!
This is no trick question, just a clever solution.curtybirdychopper

He can flip as much as he wants with the door closed, but once he opens the door, he can do no more flipping. And i'll add he can only open the door once to find out if he is right (and if he gets his hot podium chick (or podium man if you're a woman)).

Get someone else to do it. The cyclist only gets one chance, but you say nothing about anyone else.

Flip up two of the switches open the door and if the light is on great flip one of the switches off, if it turns off its that switch if it doesn't its the other. If he opens the door and the light isn't on he knows which switch, the one that was left in the off position.

I think its supposed to say flipping on, thus you can flip OFF.chopper
Dec 4, 2002 3:07 PM
sorry, no flipping with door open. but getting closer...curtybirdychopper
Dec 4, 2002 3:07 PM
biker girls good!
clue: what happens to bulbs when left on? nmcurtybirdychopper
Dec 4, 2002 3:27 PM
clue gives it awayishmael
Dec 4, 2002 3:37 PM
flip it on then off and go in and see if the bulb is hot
they burn outmohair_chair
Dec 4, 2002 3:38 PM
It kind of defeats the purpose, doesn't it?

Okay, flip a switch, feel for warmth. Repeat as necessary.

Question: what do the other switches do?
Question: what if the walls are too thick to conduct enough heat?
Question: what if the shed catches on fire?

Flip one switch and wait a few minutes. Then flip the 2nd switch and immediately enter the shed. If the bulb is already hot, it's the first switch. If it's on but not hot, it's the 2nd. If the light is still out, it's the 3rd.
This is technically the first correct explanaiton!curtybirdychopper

Nice going housemoney!

Ishmael had the idea, just didnt explain it well.

and your prize housemoney:
One more question!Qubeley

Standard switch. Too late anyway quebley. sorry.curtybirdychopper

Check the power meter on the side of the shed. It is probably moving very slow, if at all.

He flips one on, and checks the power meter on the side of the shed. And so on, until he finds the switch that causes the power meter to increase its velocity. That is the right one. Opens the door, the light is on, and he sees:

Nightmares of RBR past: cyclist jumping great wall of china, Trolling Campy Vs Shimano (Do you smoke pot while riding MasonJ?), ridiculous heaps of stem spacers, and a podium girl with a mustache. A nice, strappin' one from the Australian outback.

Dec 4, 2002 6:02 PM
Flip one switch off and on really rapidly for a while until you hear a pop! and glass shattering. If you don't hear it for a while,move on to the next switch. Repeat until you hear a pop. when it pops,it's the switch that you were flicking on and off. Ta da!
easy peazy...hayaku

He only needs one chance to find out if he/she flicked the right switch. If the light is on, nice pick but if it isn't, he/she still knows whether or not he/she got the right one. That was the question.

Personally, I'd leave the door open and flick to my hearts content. Having only opened the door once I can satisfy the terms of the challenge and still find the correct switch. Yay!

real solution!floatch

I didn't read all the above solutions, so please don't flame me if someone's said this already...

For switches named "A, B, C".

Step #1- Turn on switch A. Leave on for about 10 minutes. Turn off switch A.

Step #2- Turn on switch B.

Step #3- Open door and see if light is on.

If light is on, it was switch B. If light is off AND COOL, it's switch C. If light is off AND HOT, it was switch A.

How's that?

Got it right Floatch! Okay, i'll start another puzzle above!!!curtybirdychopper
