TO check the suitability of a given strut cross‐section, for a given length and safe concentric working load, is a simple matter provided that a working stress curve or formula is available, but the reverse process of obtaining a suitable cross‐section, for a given length and load is under normal circumstances a tedious trial and error task, unless comprehensive tables of the properties of the required section arc available. The author's method permits a very close first approximation to be obtained, which is frequently sufficiently accurate to enable the required cross‐section to be laid out without further trial.
