Flintstones physics: how much does that rack of dinosaur ribs weigh?

The scene: the closing credits of The Flintstones.

Fred, Wilma, Dino, and their cat go to a drive-in restaurant. A waitress brings them an enormous rack of dinosaur (or other large animal) ribs. Once they’ve been placed on the car, however, the car tips over because of their incredible weight.

How much would those ribs have to weigh to tip over a car made primarily of wood and stone?

(This is just one piece of evidence that homo bedrockus was much stronger than modern man – that car gets around at a zippy clip through the courtesy of Fred’s two feet, after all.)

I really have no idea, but I figured there was no better group of people to ask.

Yes, I’m serious. Anyone able to come up with a good guesstimate?

(Mods: I was on the fence about GQ or Cafe Society. Sorry if I chose the wrong door.)

Another would be the fact that although the rack of ribs is heavy enough to tip over a car, a slender waitress carries them around with ease.

Most of the weight in Fred’s car is going to be in those two big stone rollers in the front and back. I would estimate them to be about 1.5 m long and 80 cm in diameter, which (assuming granite has a density of about 2.7 g/cm[sup]3[/sup]) gives them a mass of about 360 kg each.

I don’t have enough time to do the moment of inertia calculations right now, but given the geometry of the situation I wouldn’t be surprised if the dino ribs weighed over a metric ton.

Yeah, but it’s mostly bone, so there’s not that much eatin’ on 'em[/missing the point]

How about MPSIMS? I just couldn’t do it to Uke, my John Thorne buddy. :slight_smile:

Just to let you know, I’m totally assigning this question to my Intermediate Mechanics class.

I just made it a project in dynamics to be made in Maya 3D, will post some results if I have the time before the trip to the SF bay area.

Look at Google images and enter “flintstones ribs” for reference images.
