Subject: Fw: Barrier: READ FIRST THEN WATCH THE VIDEO
How many times have you wondered how strong those cement barriers are that you see in front of military base entrances? This was sent by someone who works for the Army Corp of Engineers.
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.
Truck = 65,000 lbs. ~
Speed = 50 mph
Kinetic Energy = 5.5 MILLION ft-lbs
Stopped in 24 inches!
