I don't understand the puzzle myself,
There are two wheels touching each other circumferentially. The radius of the big wheel is 4 times the diameter of the smaller one. The outer small wheel rotates in anticlockwise direction circumferentially over the bigger one at the rate of 16 rev/sec. The bigger wheel also rotates anticlockwise at N rev/sec. What is 'N' for the horizontal line from the centre of small wheel always is horizontal.
maybe if it was worded better. preferably in English.
i'm geussing 8 but that's only for two not very mathematically sound reasons. The big one has half the diametre of the small one. It seems that we are trying to keep the small one in the same spot by rotating the big one ata speed that will do that so i geussed half the spee the small one is going.
and 8 is my lucky number.
good luck though
Boephe, the diameter of the large one is 8 times that of the small one, not half.
I would go with N=16, but I'm not sure about that based on the riddle as worded.
I personnally think that this is a complicated maths question. In fact i think that they should make a new forum just for maths boffs who want to spend their time lookin at riddle/maths questions cos they cant take the real riddles. Yeah
Sorry, bit of a rant then
U know had a hard day.
Whateva!
