Crack on 1/2" tempered glass table top

6 weeks ago I purchased an allegedly tempered glass, 40x66x1/2" rectangular table top with rope (shell) edge. It had previously been on table in a furniture store show room and appeared to be in perfect condition there. I placed it on a 16"X48" rectangular pedestal base for the first couple of week and transferred it to its present 22.5"X44" oval, rattan base 16 days ago. The crack is in the overhang that extends 11.5 inches from the end of the base (The opposite overhang is slighly less).

Help - Glass Strength

Hi, I'm a student at Iowa State University and my classmates and I are looking for help with a problem. He need to know how to calculate the flexural strength of glass, tempered and otherwise if possible. We are trying to decide if a glass panel in a railing is adequate to meet building code, which is 200 pounds per 1 square foot.

Any help would be appreciated.

Thanks, Jamie
