I am trying to determine how much force is necessary to make a round table topple over, or what information I need to make such a determination. The table is 30" in diameter and 1 1/4" thick, made from medium density fiberboard (MDF). The MDF has a density of 39 lbs/foot3. The table has three legs, equidistant from each other, placed at the edge of the table. The legs are made of aluminum, but I do not know their weight or exact size. The legs are 22 1/4" in height and are secured directly to the bottom of the table. Is there a way of roughly calculating how much weight would be required to topple the table if the weight were placed precisely between two of the legs at the edge of the table?
