TīmeklisRankine-Gordon's empirical formula is known as Rankine's formula. The Rankine formula is therefore valid for extreme values of 1/k (means for short and long columns). It is also found to be fairly accurate for the intermediate values in the range under consideration. Note: Crushing load is responsible for the failure of short columns.
