Hi there. I have come to this forum to try and find someone able of helping me with some (im sure) basic Physics. I'm trying to work out the Physics behind the Prosthetic carbon fibre legs that Oscar Pistorius uses, a diagram would be incredible! I want to know what calculations would be involved in working out the angles of the blades and how to work out the thrust. I understand this is probably a pretty simple question, but it has been a long time since high school! Many thanks.
