* a and b = either side. 2a + 2b = number.

Example

What is the weight per lineal foot of a 12" X 16" X 1" thick column?

Ans

2a+2b = 24+36 = 56. Opposite this number, under 1-inch thick metal, we find 162 5, or weight per lineal foot of a 12" X 16" X 1" thick column.

Note. - For flanges, brackets, etc., calculate the cubical contents of same and multiply by .26; cast iron averaging 450 pounds per cubic foot.
