comment What should I consider when cutting/making window in concrete foundation?
Can you provide better photos of the crack. It is possible that the crack has formed because there is a lack of a lintol over the opening to support the wall. If this is the case then creating the opening is likely to result in a number of issues.

comment How can I cut through brick to add a window?
Is that wall load bearing? If it is, there seems to be two windows either side and so you could be cutting away at a wall that supports the lintol for the two windows on wither side. If you are not sure I would definitely seek advice on this one before cutting.

comment Why might a weld be weaker than a bolt?
One other issue to note is that for many bolted connection details (although not all) the connection fails in a ductile manner, giving some warning prior to failure. For many bolted connections this is not the case. For critical connections it is not just the plane strength of the connection that is important but also issues like durability and ductility.

comment How much load can a (wood) board support, if it is supported only at the ends?
@evil otto, the simply supported beam equations and the fixed fixed beam equations are actually really simple and you won't need to use differential equations. raeng.org.uk/education/diploma/maths/pdf/exemplars_engineering/… might be a good start.

comment How much load can a (wood) board support, if it is supported only at the ends?
The nice thing about using simply supported beam for a simple plank is that the bending forces and deflections will be maximum values. If you use a fixed-fixed model there will be some worse bending moments at the ends but they won't be any greater than the mid-span moment for a simply supported case, but that is fine if your beam is the same thickness all along.
