Problem Eight: Bad Bird, Bad Bird!

Here’s another interesting brain teaser I found on the Internet. It actually has some practical implications in technology.
An 18-wheeler is crossing a 4 kilometer bridge that can only support 10,000 kilograms and that’s exactly how much the rig weighs. Halfway across the bridge a 30 gram sparrow lands on the cab, but the bridge doesn’t collapse. Why not?
