    Following the depressing speed with which you clever sods solved logic puzzles 3 i humbly present logic puzzles 4.

    I regret that i am now out of attaboys so the prize will be in the form of Goddonyas.

    1.
    One brick is one kilogram and half a brick heavy. How much does a brick weigh?

    2.
    A train leaves New York for Boston. Five minutes later another train leaves Boston for New York, at double the speed on the same line! Which train will be closer to New York when they encounter?

    3.
    The circumference of the globe is approximately 40,000 km. If we made a circle of wire around the globe, that is only 10 metres longer than the circumference of earth, could a flea, a rabbit or even a man creep under it?

    4.
    A man is locked a sealed, locked and comletely empty room. There is a hole in the floor 15 cm deep and only fractionally wider than the table tennis ball which has been dropped into it. The floor is made of solid concrete to a depth of 30 cms.
    How can he get the table tennis ball out of the hole?

    5.
    Why can't a man living in the USA be buried in Canada?

    6.
    Is it legal for a man in California to marry his widow's sister? Why?

    7.
    If there are 3 apples and you take away 2, how many do you have?

    8.
    How far can a dog run into the woods?

    9.
    One big hockey fan claimed to be able to say the score before any game. How did he do it?

    10.
    Why do Chinese men eat more rice than Japanese men?

    11.
    What word describes a woman who does not have all her toes on one foot? (a clue, the answer is NOT diabetic).

    go on then, i'll take the easy ones

    5. coz he ain't dead yet

    6. not sure whether it is legal for dead people to get married anywhere

    7. 2

    8. at the risk of falling into a cunning trap i'm gonna say half way coz after that rover is on his way out of the woods (straight past the bear:D)
     
  3. :D

    Is this a man quiz cos I don't get it. May we please have more knitting or crochet problems please.
    Thanks muchly .
     
  6. From the book of Pod, chpt 4

    1 And lo a voice spake from the heavens 2 and it spake saying 3 "art thou not so sharp thou shalt cut thyself? 4 You Smartarse?" 5 And the philistine was dismayed 6 for the answer he gave was not the answer sought 7 though technically correct.

    Alright. Empty except for the man and the ball. :rolleyes:

    Sorry twirly. I'll try to find some more ferminine ones.;)

    did anyone answered.....????
    #2 Well, when they CRASH I guess the train that LEFT NY will be a bit closer because it's on the south side of the track. Otherwise; at the point of impact will be the same for both.

    I'll venure #3 is none of the above can.

    #4 well..the only thing I can think of is if he urinates in the hole it will float up and he can crab it!

    Back to work

    No 1 A brick weighs 1 (one) kilogram

    No 9 The score before any game is nil :nil

    No 10 Chinese men eat more rice than Japanese men because there are more Chinese men than Japanese men alive :rolleyes:

    Think that I have one or two here.

    1. One kilo

    3. All can because what is under consideration is getting under a 10m length of wire, not the circumference of the earth

    4. It might be faintly possible to suck the ball out but I prefer Steve's idea of peeing in the hole. I wouldn't want to suck the ball after that!

    9. The score before any game is 0-0. Alternatively, he could simply say 'the score' before the commencement of the game

    10. Because there are more Chinese than Japanese men. Alternatively, thinking laterally, because they have more rice

    11. Bi-pedal or normal or who has not suffered amputation of one foot

    These puzzles do lead to abstruse ways of thinking. Thanks, and keep 'em coming

  12. Correct. at the point they crash they will be the same distance. Or if you want to be anal Most of the NY train will be closer.

    Ha. Wrong.

    Correct. widdle in the hole and the ball will float out.

    wrong. Read the question. the brick weighs one kilo and half a brick.

    correct and correct!

    Wrong

    Wrong. and smug. The question is what happens if you take your wire which goes around the earth, add 10 M to its length. How high off the ground will it now be?

    ewwwwwww!:dizzy:
    correct

    [/QUOTE]

    correct. Somebody who does not have all ten toes on one foot? Normal i would say!

    :confused: Did you just make that up? :rolleyes:

    Well done to all. share a big GOODONYA between you. That leaves

    Obviously Podiatrists are better at lateral think than maths. In spite of Kevins best efforts!

    3. No, not smug, just trying to apply logic. Perhaps I am thinking too much in straight lines, but, if the wire was raised there would be 5m each side, by lowering again slightly, an equilateral triangle could be formed 5m sides. Therefore, any of the beasts mentioned should easily get underneath.
    I suppose that it could be argued that if the wire is lying on the ground then nothing could get under it, but that is pure sophistry:dizzy:

    1. One kilo and half a brick.

    All the best


    Bill
     
  14. :D
    The wire has not been raised. it has been cut and 10m added to its length.

    In other words it was 40 000km, the exact circumference of the earth (for the sake of aguement.) assuming that you have added 10 m to its length so it is now 40,000.010km long and assuming the wire is raised an equal distance all around the globe how big an animal could crawl underneath?

    Which is what, in kilos?

    Having fun?:rolleyes::p

    1/ 1/2 a brick must weigh 1kg so 1 brick must weigh 2 kg .................... i bet that scottish cow would want to get under that rope, more fun playing limbo than you-know-whatting
     
  17. Nice one mark, right on both parts.

    Which scottish cow woulf that be?

    Best i go find some more!

  19. A kilogram is not a measure of weight, it is a measure of mass. A kilogram in a weightless environment (i.e. outer space), would have no weight. Also, an object with one kilogram of mass would weigh different amounts depending where on earth the measurement of weight was being made due to the different values for the acceleration of gravity depending on the location on earth.:bash:

    Kevin, how much less would anything weigh, say between the top of mt everest (8848 m) relative to mean sea level?
     
  21. W J Liggins

    W J Liggins Well-Known Member

    Trouble is, we could play these games forever. How much would Robert's 2kg brick weigh, for instance on the moon and on Jupiter?

    If a kg. is a measure of mass, what is it's energy x acceleration squared? Is it enough to penetrate a computer screen?

    Always the same with research isn't it, you end up with more questions than answers.

    Still puzzling

    Bill:bang:
     
  22. Mark:

    Actually, the largest variation in earth's gravitational acceleration on its surface occurs not between its highest point (Mt. Everest at 8,848 meters above sea level) and its lowest point (Dead Sea at 418 meters below sea level), but between the equator (equatorial radius of earth = 6,378 km) and at its poles (polar radius of earth = 6356 km) or a difference from the center of the earth that is nearly 2.5 times the height of Mt. Everest above sea level.

    The acceleration of gravity at the North Pole is 9.86 m/sec^2 and the acceleration of gravity at the equator is 9.80 m/sec^2, if we neglect the rotation of the earth. With the centrifugal force of the earth factored in at the equator, the net acceleration at the equator would be 9.76 m/sec^2, since the rotation of the earth will tend to accelerate objects on the earth's surface away from the center of the earth. http://www.ac.wwu.edu/~vawter/PhysicsNet/Topics/Gravity/AccOfGravity.html

    Therefore, for a 1.0 kg brick, the brick would weigh 9.76 N at the equator and weigh 9.86 N at the North Pole. In other words, the brick would weigh .0225 pounds (0.36 ounces) less at the equator than it does at the North Pole.

    Not a lot of difference, for sure. But since the logic puzzles are "trick questions", then I thought it would be nice to throw a curve ball back to Robert to see if he could hit it. :drinks

    I refer you to my national team's performance at cricket. Hitting balls is obviously not something we're good at. :rolleyes:

    I can't argue with your logic. But i might call you a pedant.

    Kevin, thanks for the reference, went over it a few times, question why isn't it the centrifugal force which is factored in factored in (greater at equator with larger radius component). Isn't the gravitational force the centripetal force and the rotation the centrifugal force. If i've explained myself lucidly, what's going on? I realise a positive centrifugal force (vector direction outwards) is a negative centripetal force (vector direction inwards) but why is the 'rotational' force referred to as a centripetal force?, thanks, mark c
     
  25. Mark and Robert:

    Mark: Thanks for that correction on centrifugal/centripetal forces....I have now corrected my last posting. Yes, the gravitational force would be a centripetal force and the rotation of the earth is a centrifugal force.

    Robert: A kilogram is a still a mass, not a weight. I remember this from my high school physics course, 33 years ago. The term "pedant" seems to be used to describe a person who points out an error in the use of scientific terminology on a website intended for medical professionals only by the individual who originally made the error in terminology.;)

    Ok ok. I give in.

    Terminology fascist!!!! I'll be watching you're every post like a hawk from now on. Just you wait! Next time you say something weighs X LB or Y Kg i'll be down on you like a cat on a feather!

    :butcher:

  27. Robert:

    Here in the States, items are still commonly measured in a force value, in pounds. We buy a pound of butter, or a pound of coffee. While, if I am not mistaken, in most other countries, items at the grocery store are measured in their metric mass equivalent, such as grams or kilograms. To buy the item with equivalent terminology here in the States, items would need to be sold in units of mass, or the venerable "slug". Of course, most people here in the States don't have a clue what a slug is, and I'm sure it is not a unit of measure that is still commonly used anywhere. Therefore, I hope you see my point in trying to keep our discussion of units of mass and units of force clear, unless of course it is used as a question in one of your "logic puzzles".:rolleyes:

    And, one other thing, I don't mind being corrected if I am using incorrect terminology.....in fact, when I am corrected publicly here on Podiatry Arena, I am rather glad that someone has paid sufficient attention to my posting, has good knowledge of a subject and has enough confidence in their knowledge [as Mark did recently in my error on centripetal/centrifugal terminology] to be able to point out my error so I can correct myself. I always gain increased respect for those individuals who know more than I do and take the time and effort to inform me of my errors. How else am I to learn??
