Logarithmic Charts as an Aid to the Designof Struts

0NE of the many difficulties with which the designer of struts has to contend, lies in the fact that most of the accepted formulae are designed to enable the safe load for a given strut to be ascertained, but not to give directly the size of strut which will stand a given load. This means that the selection of strut sections is a process of trial and error, and a very tedious process at that, if,the maximum economy is required.
