I have prepared a 7.5 ft x 2.5 ft piece of monkeypod wood that is approximately 2 inches thick. It will serve as a computer desk. The heaviest object on it will be my desktop tower (~25-30 lbs). You can see pictures below of the wood and the legs.
How do I decide where to place the legs? Ideally, they would be at the very ends because that gives the most leg room underneath. But I don't want the table to sag in the middle or eventually break over time. Should I move the legs in from the edges and if so by how much?
