Yep, sorry you're quite right it's kN. I could give excuses about it
being a typo, but looks like I've written it twice. I could use the
excuse that I don't know what Nm are, but I own a couple of torque
wrenches. I could use the excuse that it was late, but the post was at
20:52. So I'll quit while I'm behind :D
The interesting thing is the pier only needs to be rebuilt from the cill
to the lintel level. I would have through that the blocks directly
under the cill level would have been under 57kN force, but he seems
quite happy that the force dissipates through the wall under the window.
If you imagine pulling a lintel out of a wall, e.g. from over a door,
the wall doesn't collapse vertically above all the way to the top of
the building. It's just a triangle of bricks over the door which fall
out. The rest are supported by transfering their weight to the wall
either side of the door.
