Hi all I fly model planes in combat and need to build a wing that will withstand a head on impact! I am going to use epp foam to form the wing and a carbon spar
the foam will be cut at the spar line and the spar will be a H rotated 90deg so that the foam slots in either side
what I need to know is how strong do I need to make the spar
so its 2 objects both traveling at 50 mph impacting on a surface area of 1 inch
I assume that's the same as 1 object impacting an imovable object of 1 inch at 100 mph
but that's all I know as I am a rather thick so if you could tell me the answer and also explain the calculation Id really appreciate it
kind regards goony
