Universial Ball and Socket Joint

This is a universial ball and socket joint. The grove around the edge of the socket is for an o-ring [ OD = 1-7/16" ID = 1-5/16" WALL 1/16" ] designed in order to keep the ball from coming out. This part is apart of a project for Humboldt State University ENGR 215 and was design for SCRAP Humboldt. Please visit this page if you are courious what it was used for.
