A Thread for Random Videos

Showed videos in mechanics class today. We're doing conservation of momentum right now, so lots of collisions, and a bit on rockets. I've linked these videos to these boards before, but not in a couple of years.

  • (Crash test dummy, with and without restraining devices. About a minute long.)

  • http://www.petapixel.com/2010/04/26/apollo-11-launch-at-500-frames-per-second/

    (First half-minute of the Apollo 11 launch, captured at 500 frames a second; about 8 minutes long. The narration is a big plus.)

  • (Film of a test done in 1988, colliding an empty F-4 Phantom into a concrete wall at 480 miles per hour; about 7 minutes long. Silent. The wall is just over 3 meters thick, and is intended to be a mock-up of a reactor containment vessel. The point was to see if flying a plane at speed would breach the vessel. You can see the wall's recoil -- it's on shock absorbers -- starting about 3:45, and again at 4:00-4:10 and 4:35-4:45. On the second impact sequence in the video, you can see the wingtips go flying past the wall. Those are the only macroscopically identifiable pieces of the plane after the collision.)
