Why are weights hung from engine mounts on empty a/c?
So I'm browsing flickr and airliners net and I found 2 recent pictures of boeings 787 with the engines off, and what's described as a large concrete block hanging from the engine mounts.

Does anyone know why they hang these "weights" from the engine mounts? What purpose does it serve?
thanks,
Jen
