How do you pick the size of the ceiling joist and why?
The factors that are involved are the span you are covering, the type of roof and the pitch of it. How you are bracing the rafters. Wider the span, wider the joist. 2x6 is usually enough for most house construction.
Will a w-8x18 carry the weight of a basement load wall 2x6 over a 20 ft span?
Yes, a W-8X18 will carry the weight of a basement load wall 2X6 over a 200 feet span.
Why is your ceiling bowing?
Could be a couple of different reasons.... Your ceiling joists could be longer than the recommended span for the size of the joist [ie: 2x6 or 2x8], and over time the weight of the ceiling material and whatever is directly above them may be bowing the ceiling down.... or In older homes with plaster ceilings with wood lath instead of gypsum sheet panels [sheetrock], the plaster sometimes breaks free from the wood lath and sags. This especially happens when there has been a water leak above the ceiling at some point......
How do you repair a sagging ceiling joist?
There are several ways, but probably the easiest way would be to temporarily buck under the afflicted ceiling joist with a 2x6 temporarily, until the joist is in line with the others. Then go into the attic and cut and attach a 2x6 to the joist and vertically to the roof ridge. Remove the buck. The joist should stay in place.

What does 2x6 times 3x2 equal?
It is equal to to 72 because 2x6=12 and 3x2=6 and 12x6=72 or if you think this is to complicated, you can do 2x6=12, 12x3=36, and then 36x2, which then also gives you 72
What is the maximum span on a double 2x12 beam supporting 2x8 ceiling rafters and an acoustical ceiling?
Depends on the area above the ceiling joists. Is it a live load (living space) or dead load (just the joists with maybe an attic above)? Also, the length of the ceiling joists from the last bearing point is a factor. How much weight is bearing on the beam is the critical issue.
What is 2x6 5x3 - 7x4?
An expression. It can be factored out slightly too: 2x6 + 5x3 - 7x4 = x3(2x3 - 7x + 5)
