Abstract: This program selected the lightest standard pipe which will

carry a given eccentric load for a given height. Schedule 40 and Schedule

80 pipes from 1 to 12 inches are included in the data table. The program

returns the size and schedule of the pipe having the least area (or weight)

which will give a maximum stress less than 20,000 psi.

The usual engineering judgments must be made in selecting the input

data. For example, the column length must be the Euler length, which

depends on the mode of support for the particular column. Care must

also be taken in the selection of eccentricity values, as values near zero

are unrealistic. The secant formula is used for computing the maximum

stress; limitations to the use of this formula must be observed.
