Control arm? Part identification help.

Hello all,
I'm new here, and new to vehicle repair/parts in general. Today I found 4 of these things, and for the life of me, cannot find an image anywhere on google that shows a similar part. Any help is appreciated! (Also, I don't need any specific info such as manufacturer, etc., just the general type of part.)

They look like part of an engine stand.
