Thread: Weight & Torsional Stiffness

  1. #1
    I need some reasonable values for both weight and torsional stiffness
    thanks in advance

    "I need some reasonable values for both weight and torsional stiffness

    Do you? OK.
    A medium sized dog might reasonably weigh 10-15kg
    A block of edam cheese has a torsional stiffness of around 0.1 Nm per degree, as a reasonable estimate.
    Now, my turn. I need a new computer.
    Thanks

    Geoff,

    I normally appriciate your postings throughout this forum. But this post is just stupid.

    A torsinal stiffness of cheese should be only 0.1 Nm per degree? We measured over 10 times this value on low-quality Swiss cheese with HOLES in it!

    Please think before posting such wrong numbers, you throw those people of.. they believe you. With great power comes great responsibility!

    Come on, really?

    That weight for the dog doesn't seem right either... 10-15kg dog can't even breath with all this snow, so that's definetly below average!

    we tried using sharp cheddar once for its increased stiffness but its also rather brittle. No useful data was gained from the experiment and munster was chosen as an alternative.

    We actually saw some promising results with cheddar. If you cure it properly it will be exceptionally stiff and reduce weight by getting rid of it's extra moisture. American (read processed) cheese on the other hand...didn't change at all. Not even mold. Curious. Cheddar is practically carbon of the cheese world!

    While a feel a nice sharp cheddar indeed is the stiffest, you have to watch out for the brittleness that has been mentioned prior in the thread. I've taken a preference to Gouda or Mozzarella in this aspect. Mozzarella is definitely the softest, but it is AMAZING in tension. Gouda has nearly the stiffness of mild cheddar but with a much smoother consistency.

    Now, if you could somehow reinforce the cheddar with mozzarella, then you'd be on to something.

    Also, should be noted that other than Swiss which changes due to aeration properties (may want to contact your local Concrete Canoe team about that), all cheese is nearly the same density, which makes calculations convenient with regards to weight.

    Also, for regards to weight, you now owe me a beer: http://www.aqua-calc.com/page/density-table
