NASA EAS pipe version

The rewritten text for the NASA EAS challenge: This solution showcases two types of support, with one being mirrored, made from aluminum or stainless steel. Stainless steel is stronger according to FEA analysis, but an alternative is making it from aluminum and increasing the pipe diameter, although this might require reducing the experiment's keep-out area. The aluminum version weighs 1,04 kg (2,294 lb), while the stainless steel version weighs 2.7 kg (6,05 lb). Advantages of the design include: a) No bolts or screws are needed for assembly in orbit. b) Two V-shaped pipes result in a compact package. c) The pipe itself generates tensioning force and acts as a wrench. d) Eccentric fixing ensures faster assembly compared to threaded bolts, but if mass is more crucial, using a typical eccentric handle can be avoided. Handles require additional length and mass (4x), which may increase cost when a screwdriver already in orbit could be used. e) A mounting plate with four simple laser-cut patterns ensures fast assembly time and pre-assembled 4 fixing assemblies.
