I am curious, how can I figure out how many extensions my LX arm would carry? For example, I currently have a TV mounted which weighs according to the Amazon specs 6kg / 13,2 pounds. The LX arm is wall mounted into a concrete wall (should be very stable) and it already has two extension arms. I'd really like to use another extension arm, but I'm a little skeptical whether the weight on the mount will become too high. My guess not knowing too much about physics is that the the weight increases in a non-linear fashion on the mount with each extension arm. Is there either any one with some experience here whether this should work or even better someone who is able to tell by calculation?
Thanks a lot
