How many times have you wondered how strong those cement barriers are that you
see in front of military base entrances and around all Federal buildings?
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 !!!How many times have you wondered how strong those cement barriers are that you
