Engineering Quiz

July 24, 2006 9:32:59 AM

A backhoe weighing 8 tons is on the back of a flatbed trailer and heading east on Interstate 70 near Hays, Kansas. The extended shovel arm is made of hardened refined steel and the approaching overpass is made of commercial-grade concrete, reinforced with 1.5 inch steel rebar spaced at 6-inch intervals in a crisscross pattern layered at 1 foot vertical spacing.

Problem to solve:

When the shovel arm hits the overpass, how fast was the vehicle travelling to slice the bridge in half? (Assume no affect for headwind and no breaking by the driver).

Extra credit:

Solve for the time and distance required for the entire rig to come to a complete stop after hitting the overpass at the speed calculated above.

Answer:

Who cares, the trucking company just bought themselves a bridge.

Additional questions:

Why did this backhoe get transported with the scooping arm in such a verticle position?

How in the world did the driver -not know- that the item he was transporting was too tall to fit under the bridge in question (by the looks of it, by at least 5ft or more)?

Whenever death may surprise us, let it be welcome if our battle cry has reached even one receptive ear and another hand reaches out to take up our arms.

I dont know about anywhere else but in Quebec its rare to see a construction worker working, 9 out of 10 times they're on break on standing around doing nothing. And that more than 5 feet probably 8 or higher.

Amen to that Rogueboy, hence the reason I hate blue collar workers.

Anyways, that definatly made me laugh. Seems like something that would happen in a movie.

the worst part about this whole thing is that I actually looked it up because a co-worker thought it was fake, thats a real scoop and it was in the kansascity.com newspapers website, as well as the date of the picture a day off from when the story was published.
