Free simple physics program for simple designs

guitarguy84

I am looking for a very simple downloadable program that allows me to create simple 2D designs of mechanical parts. One that lets me quickly create links/ pivots and move them to simulate movement. Almost like a Google Sketchup but for engineering and even simpler. I am not looking for a game with some sort of objective...just a testing program.

Thanks

How about FreeCAD (3D) or QCad (2D)?
