We have one of those coffee tables which is basically a piece of glass sitting on a steel frame, and I'd like to get an idea of the maximum weight it can safely support - but I don't know how to work it out. The glass is only point supported in 4 places, where it sits on 30mm diameter metal pads which are epoxied to the glass and sit on the frame (they have a peg which locates them). The glass is 1200*660*12mm and the supports are at the edge of the longest sides, 220mm in from the ends.
Any ideas how to work it out, or a reasonable guess as the maximum weight would be helpful - I might want to put a TV on it... ;)
