Thank you, Sam. I opted to simplify the problem and saved up to purchase a new, thicker post. imgur.com/zK8gJP0,dTYrsn1,s1aH3z4,zHQgZ4w,CzwBYL1#0

Lastly, for what it is worth, I will likely move the bracket down so that it covers the seam between the top and bottom pole, reducing the stress at the connection point and thereby distributing some of the weight to the bottom pole.

Thank you for a thorough analysis. The bracket fits the pole quite snugly, so adding a sleeve under the bracket would be possible if the sleeve is thinner than paper. Filling the pole is not an option (hidden wires inside the pole; needs to disassemble for moving). Making the bracket taller to spread the load would be difficult and expensive. Thanks for the ideas, though, I appreciate it.

@Anna: I did not do g^2. I used r = 520 MPa / (14 kg * (9.8 m/s/s)). Unless you mean a different value for g than 9.8m/s^2. A smaller post won't work. Take a look at how the posts are assembled in the PDF: omnimount.box.net/shared/static/v4hvzsg7r1.pdf ... Wires go up the inside of the post (as you can see in the picture), so pouring concrete would be at odds to one of the pole's purposes (hide wires). I can bolt supporting rods to the outside of the pole, though, with some care and difficulty.

@Anna: I used the following calculation: bit.ly/gm3eNp at WolframAlpha, but the answer was meaningless to me. Any idea what I've done wrong?

@Anna: Thank you. A thicker pole is not feasible (notice that the pole goes through the top of the desk---nearly to the floor). The pole is locked in place by two long, thick, pieces of wood secured to the back of the desk. A second (or third) pole is also not feasible for the same reason as a bigger pole: the desk is finished.

@Keenan: I was presuming the plates would be secured sufficiently to hold the weight. That was a rather large and erroneous assumption. Thank you.
