Load Capacity of a Rectangular Tube
Hello,
I am looking to purchase two aluminum 6063 four feet rectangular tube of dimensions 4" x 2" x 1/4". I am going to be mounting linear guides and carriages on the tubes. I am also going to mount an aluminum plate (6061) 2.5' x 2' x 3/8" in dimension. This platform would be used to translate human subjects in the forward and backward direction to test their ****** response. The maximum weight for the human subjects to be eligible for the study is 300 lbs . I would like to know if this tube would be able to support that much weight. Just for your information. We will be inserting a rectangular flat bar within the tube to weigh it down. That way, once we take the flat bar out, the platform could be moved to another location easily.
If this dimension for the tubes won't work, what are your suggestions?
Thanks!
