Physics challenge

Discussion in 'Break Room' started by Robertisaacs, Feb 4, 2011.

    So I was revisiting thought experiment 1 today, which looked at forces in trusses and such. And I had a connection click in my mind.

    Iphone. There is an app for that.

    Its called bridgebasher. Its presently free.

    The idea is you have to devise a bridge using struts, trusses and such. When you are ready the game runs word trains over it. Your bridge has to stand up to all of the trains. And the less struts you use, the less the bridge costs and the higher the score.

    The Thought experiment is about the relative angles and stresses on the joints. So is the game. Not a bad way to introduce people to fissics.

    Its hellishly addictive but if anyone fancies they know physics, my best score is a bridge which (sometimes) stands up to all the trains and costs $873. If you can beat that, I'll be impressed.

    For goodness sake Robert, the last thing I need is another app that I end up addicted to, that I have to hide from the BFL every time she comes in the room. (Angry Bird being the cuplrit previously)

    Praise be to the Lord, it's not available on Android!
     
  4. Thats a real shame Robin. Physics based challenge type game would be right up your street if you are of an addictive persuasion...:empathy:

    Oh wait, :rolleyes: theres a web based version:drinks

    The physics model is a bit less afvanced and there is no $ value for keeping score, but its still fun.

    I'm just going to pretend I didn't see that thank you very much
     
  6. You'll be back...

    Its simple. You just think about the physics, look at a few real bridges and lay one out. And if it isn't strong enough you can just walk away....

    I may give his a go but it is not free anymore, a mere .99 cents. I'm with Robin on Angry Birds. I about lost my noodle over that game already...and yet I keep coming back and playing after getting through all levels on the free app!
     
  8. Its 99 cents well spent mate.

    I too have lost many a happy hour on angry birds though.

    This one is a bit more thoughtful. You find yourself thinking about it when on the toilet or in the car. Painfully simple but horribly addictive.

    $873 is the score to beat david.

    Damn you Robert Isaacs, damn you! I'll buy the app and end up trying to beat the score of the guy that forces me to use references when reading his posts....damn you!!

    Well thanks for that Robert. You'll never guess what I spent my Saturday night doing. Can't complete IMPOSSIBLY HEAVY and my bridge to get me that far looks like the Forth Rail Bridge
     
  11. My apolgies to your partners :D.

    For your first one, where you just try to get a bridge which works, think suspension bridges. Notice which joints fail and consider the difference between tensile and compressive forces at those joints.

    If it helps, I'm stuck at 873. The best design to date is 140 and involves some kind of ramp!!

    I'm presently trying to design one with moving parts.

    If I get time later I'll upload one that works at 1200 or so to give yo a nudge in the right direction.
