Do you have anything approaching a hard sciences or engineering degree? Or practical experience in hard sciences or engineering.nope. I see only one angle (vector) in that photo.
I don't know what stinkle is on about since I don't know **** about explosives, but I do know that it takes two vectors to define a plane. I also know that the column break shown is not orthogonol to the column in any of the 3 major axis.
