I'm the sole developer for a publishing house, doing on-line courses and exams.

We have a web designer, who typically does layouts and courses, but I do anything that involves programming logic.

comment What can I do to ensure my pool doesn't freeze?
The pool will be fine. Water has to give up a whole lot of energy to freeze. What might freeze is any above ground pipes near the pump. Just keep the pump running while the temperature is cool.

comment How to replace bathroom supply line?
You need a 1/2 inch to 1/4 inch reducer fitting. These are readily available at your big box store.

comment Replacing a spanned “beam” with a cantilevered beam
While you are correct re: strength vs. deflection, for most household materials the deflection limit typically 1/240 or 1/360 IIRC, are usually the limiting factor. That is, a safe design will typically violate the deflection limit, but a deflection based design will usually be safe. (Although, all bets are off on this short span).

comment Replacing a spanned “beam” with a cantilevered beam
I'd really like to see a photo of the existing situation as well as a sketch of the proposed solution. Also, have you considered how you'll be attaching the cantilever?

The first thing you do is install a CO detector in the room above the garage!

comment What should I use to fill a gap between oak trim and wall?
Or you can try clear caulk. Test it in a corner and see if it works for you.

comment Simple software for stress analysis of wooden structures?
@LoftyGoals Yes, that's why Mechanics of Materials is important. Statics is the study of rigid, statically determinate rigid frames and trusses. (Static = not moving). To solve for indeterminate (over constrained) frames, you need to take into account material bending.

comment Simple software for stress analysis of wooden structures?
Just so you know, this type of analysis is 3rd year rigid frame analysis. You need a solid grounding in Statics, Mechanics of Material and structural analysis, as well as some pretty good matrix algebra and integral calculus techniques. There are some free unix programs around. I recall a product called SDTruss, which did FEA but it was a couple of weeks study just to figure out how to get the input file right. The sign convention was awkward at best.
