A backhoe weighing 8 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. The steel rebar is spaced at 6 inch intervals, in a criss-cross pattern,
layered at a 1 foot vertical spacing. When the shovel arm hits the overpass, how fast does the driver have to be going in order to slice the bridge in half?
Yeah, I know.....I couldn't answer the question either, but who cares! The picture is great!
