Vehicle Barriers Back to War / Back Home
Thanks to Lisa for sending this one!
How many times have you
wondered how strong those concrete barriers are that you see in front of
military base entrances?
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.
Truck = 65,000 lbs.
Speed = 50 mph
Kinetic Energy = 5.5 MILLION ft. lbs.
