Any Darwin Award nominees in there? Title: Physics 101 Post by: Shavnir on December 09, 2004, 09:36:50 AM That article would have been considerably more entertaining if it had taken a third crane.

Title: Physics 101 Post by: Calantus on December 09, 2004, 09:44:23 AM That was cool. Haven't had a laugh like that for a while. The sequence was beautiful too, I'm not sure if video could even trump it.

Funny you mention that -- someone did!! The way I first saw this was from an email from a friend, and it included 1 more (photoshopped) pic of the giant crane going in. I don't have any webspace I can upload the pic to -- can I email it to someone here who'd upload it and post it here? It's pretty funny (though to a keen eye, fairly clearly faked). Let me know, I wanna share. Title: Physics 101 Post by: schild on December 09, 2004, 09:56:06 AM schild@f13.net, n00bler.
Title: Physics 101 Post by: Polysorbate80 on December 09, 2004, 10:00:19 AM Can't help but think of "Swamp Castle" when I see that...
"Well, the King said I was daft to build a castle in a swamp, but I built it all the same, just to show 'em. ... It sank into the swamp. So, I built a second one. ... That sank into the swamp. So I built a third one. That burned down, fell over, then sank into the swamp. But the fourth one stayed up."

Title: Physics 101 Post by: SirBruce on December 09, 2004, 04:55:51 PM What I don't understand is why the crane truck didn't tip over sooner. The car was heavier just out of the water with all the water in it, and the center of gravity would have been lower. So it should have tipped then. Something else must have happened that isn't pictured that changed the balance.

Heh, got fubared in the mail server at work, after I saw them once, I went to copy the pictures and couldn't get them out. I don't know why. But here. I'll put it into words: Shoddy photoshopping job of 2nd truck going in water. ^_^ Title: Physics 101 Post by: sidereal on December 09, 2004, 05:17:19 PM Red crane needs outriggers, badly.
Red crane is about to die. Quote from: SirBruce The car was heavier just out of the water with all the water in it, and the center of gravity would have been lower. It's not the lowness of the center of gravity, it's how far to the left it is. At 90 degrees car mass is furthest out. No outriggers, so the right set of tires become the fulcrum. Down force on each side is the product of the mass and the distance from the fulcrum. Eyeballing the picture, the truck needed to weigh about 10x as much as the car for that to work.

It's not the lowness of the center of gravity, it's how far to the left it is. At 90 degrees car mass is furthest out. Not so. Look at the pictures for yourself... the car is almost exactly the same distance out when it's level with the truck. The arm wasn't straightened or anything. That's why I say something must have happened (i.e. arm movement) that isn't pictured that changed the CG.

I don't think what you're thinking is an outrigger actually is an outrigger. You can see once it starts falling in that it's an existing piece of metal.
