Engineering Calculation Do YOU know the answer?
Posted 06 January 2008 - 04:16 PM
Solve: When the shovel arm hits the overpass, how fast does the trailer with the backhoe have to be going to slice the bridge in half? (Assume no headwind and no braking by the driver who is oblivious of the situation . . )
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: Scroll down........
Answer - It doesn't really matter... The point is that the trucking company just bought themselves a bridge .

Well that goes to show you the intelligence of some people....
Actually it seems only about 4ft too tall for that over pass the way to was loaded on the trailer (improperly). The arm of the backhoe is to be resting on the rear most of the trailer, so if a situation like this does occur it will be forced off the edge of the bed and not impale the bridge like above.

yeah, same here...angle of the arm, etc. maybe somebody who's already got a degree in civil or mechanical engineering could answer this...i'm still working on mine.

just showed this to my father and his reaction was followed by some swearing and he is amazed the bridge is still standing, you got any more info on it?
