This question makes no sense. A 90 lb load per sq. ft. refers to an area. To calculate the stresses on beams supporting an area you have to know the spacing between adjacent beams as well as the span. p.s. This qn when fixed belongs in mechanical engineering.
14 x 8 = 112 square feet
14 ft x 13 ft = 182 sq ft
14 ft*8 ft = 112 sq ft 14 * 8 ft (as asked) = 112 ft, not square feet.
Do you mean inches well in ft it`s 14 ft. In inches it`s 168 inches.
That really depends upon the load you need to carry and the material that the beam is made of.
Roof Line 30 Foot Span
1 ft by 1.2 ft... verticaly 1.2ft
That always depends on what the beam will be carrying. You will need to consult a building contractor to size any beam correctly. IT ALSO DEPEND ON ITS MATERIAL &ALSO HOW MANY STOREY CONSTRUCTION REQUIRED ON THIS
Adult octopus weigh around 33 lbs, with an arm span of up to 14 ft.
There is no upper limit provided strong enough materials can be found and used. The longest suspension bridge is the Akashi-Kaikyō bridge in Japan at 1,991m.

500 ft to 3000 ft
This can be done, but the board will be unstable and may not hold up well without strong braces, it would be better to nail two 10FT boards together with strong braces. Or it capable to make the beam into triangles, because a triangle is the strongest source that has been tested.
For ceiling joists, the minimum dimension per the IBC is a 2 x 12 inch, with spacing dependent on the load. Ideally, these would be screwed to blocking between the joists.
