Girder

The water came up to the bridge girder in a second.

The girder could not support such a heavy weight.

The girder is a 15 meter long, 13 metric ton framework that is packed with several kilometers of tubing and wiring to support cooling, power, and data relay equipment for future research laboratories.

Space station ground controllers will test their ability to command a small flatcar to roll along tracks on a 13-meter girder that space shuttle Atlantis astronauts mounted on the station last week.
