1. To carry out a materials selection exercise for a military/surveillance portable infrared imager tripod. The exercise will be carried out by means of any legal and valid technique possible and applicable, including (but not withstanding) techniques described in lectures, textbooks & crowd-sourcing. 2. No equations needed at this stage. :) 3. The main focus is on the choice of a material suitable for the legs of such a tripod. I've managed to source information related to the function of the tripod & constraints the materials I am looking into must meet. Conditions such as being lightweight (density), capability to hold a load 'comfortably' (mechanical aspects) as well as holding up to environmental challenges. Thus my idea would be to have some sort of bulk material (probably a metal or composite) along with a compatible coating of some sort such as a) specific surface treatment, b) Rubberized pain coating to protect from oxidation/corrosion. Ultimately what I am asking for are suggestions to materials which could be relevant and which I can look into further. Thanks for reading!
