Subject: Vehicle Barrier
This is an interesting film clip on brute force. It is only 20 seconds long.
Turn up the sound if you have audio so you can hear the impact. How many times have you wondered how strong those cement barriers are that you see in front of military base entrances???? Read below and then view the clip...
From time to time someone asks what the concrete barriers are in front of controlled and secure buildings. When they are told that the barriers will stop traffic, even trucks, from approaching the secure building, some people have doubts. 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.
Stopped in 24 INCHES !!!

*This is a story which is perfectly logical to all males:* A wife asks her husband, "Could you please go shopping for me and buy one carton of milk, and if they have eggs, get 6." A short time later the husband comes back with 6 cartons of milk. The wife asks him, "Why the hell did you buy 6 cartons of milk?" He replied, "They had eggs."
