That means the joists can support a minimum of 40 pounds per square foot live load. Though, by consulting the 50 pounds per square foot live load/10 pounds per square foot dead load table, you can see the joists' span would need to be reduced to 11 feet 11 inches to support heavier weight safely.
Depending on various factors, the maximum span for a 2×8 floor joist is 16' 6”. The maximum span for roof rafters is 23' 9”. For headers, the maximum span is 11' 2”.

1/4The American Wood Council states that cantilevers are limited to 1/4 the span of the joists. Joist Spacing (o.c.) Maximum allowable overhang cannot exceed 1/4 of the actual main span.

Span is determined by species, grade, dimensions, spacing, use, and load. A rule of thumb is 1.5 times a joist's depth but in feet when spaced at 16” centers. In general, a 2×8 will span 1.5 x 8, so 12-feet. Based on all factors though, a 2×8 joist span is 7'-1” to 16'-6”, and a rafter 6'-7” and 23'-9”.
A: Calculate weight, Mike, using the formula: density × volume. Well-dried, seasoned oak has of a density of about 3.6 pounds per board foot. Now find the board footage of your lid by multiplying its length, width, and thickness, and dividing by 144.

Many believe yeast will feed on cornstarch. Cornstarch is the main ingredient in many baby powders. As part of an ol d er study from 1984, researchers tested for this and found no correlation between cornstarch use and increased yeast growth.
