READ THEN WATCH




How many times have you wondered how strong those cement barriers are
that you see in front of military base entrances?Huh

Read below and then view the clip...

From time to time someone asks me what the concrete barriers are in
front of controlled and secure buildings. When I tell them that the barriers
will stop traffic, even trucks, from approaching the secure building I
usually get a look of disbelief.

I've been looking for some footage like this to prove my point. In
this test, the following parameters were used. Read them and then watch the
film.

Truck = 65,000 lbs.

Speed = 50 mph

Kinetic Energy = 5.5 MILLION ft. lbs. Remember: KE=MV2

Stopped in 24 INCHES!!!

That's insane! It even bursts into flames....I thought that was just hollywood stuff!

Any chance you got that from a few different angles. That was awsome!

I cannot claim that video. I got it from a friend of mine. It is very cool nontheless.

Holy Thats crazy and leaves me speechless.
