ALL YOU ENGINEERS OUT THERE!!



Challenge yourself here:

A Excavator weighing 18 tons is on top 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 1/2 inch steel rebar spaced at 6 inch intervals in a crisscross pattern layered at 1 foot vertical spacing.

Solve: When the dipper stick hits the overpass, how fast do you have to be going to slice the bridge in half? (Assume no effect for headwind and no braking 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 IS BELOW








Answer: Who cares? the trucking company just bought themselves a bridge!

 

I say photoshop special.

 

You can say it, but you'd be wrong...it made the Snopes as being true:

How is the untouched portion of the bridge there. I guess the hoe went up extremely fast at the moment of impact to miss that part. I call Hoax still. Not possible.

 

Ok
I know it's eating UC not to say something.....

REPOST!!!

LOL

Look at it closer, the boom is bent backwards.

Just think of the force it took to not only do that but also flatten that lowboy trailer under it to litterally an unnoticable pancake.

 

Sorry Matt, didnt feel like searching for this one.

 

I didn't see that, duh. It is past my bedtime.

 

Here is another source to prove it indeed did happen.

If you look closer it never really sliced the bridge, the top railing is intact. The top of the folded boom caught the lower portion of the bridge deck. This in turn forced the front of the trackhoe upwards and also allowed the hydraulic rams on the boom to hyperextend and shove the "elbow" through the deck.
