Re: Designing arms against buckling
there is one thing you could do..
cnc/waterjet triangles on all 4 sides of it, that way the load will be transferred throughout the tube and thus should make it stronger. Are you worried about side loads? or what type of deflection? if you were to make triangles along it it would essentially act like trusses on a bridge (if it were laying down sideways). 2x2 should be fine...then again, if you are still worried, get some machineable wax or some sort of light, hard plastic and make a core for the 2x2. |
