Blast-proof Door Hinge
How is this blast proof? Is the door inside or outside the building? Is the blast from inside the building or outside?
This is part of a WWII concrete bunker on the Somerset coast. The hinge is mounted on the outside so that the door opens outwards providing extra strength.
(I didn't expect the Spanish Inquisition...)
Best wishes,

Sorry, no inquisition intended, I was just thinking about the direction of forces and compressive/tensile/shear forces on the door and hinge components!

Oh no, my son's an engineer as well... another place where I have to get my facts right!
(No offence taken, just my heavy-handed humour.)
