Final answer:
The KL/r term, representing the slenderness ratio for a column with an unbraced length of 10 feet and a radius of gyration of 5 inches, is calculated to be 24.
Step-by-step explanation:
The question relates to the column's slenderness ratio, which is a criterion used in structural engineering to determine the column's susceptibility to buckling.
Given that the column has an unbraced length of 10 feet (120 inches) in both axes and its radius of gyration (r) is 5 inches, we can calculate the KL/r term.
KL/r is the effective length factor (K) multiplied by the unbraced length (L), divided by the radius of gyration (r). Since the column has pinned-pinned support, the effective length factor K is 1.
Therefore, the KL/r term for both axes of the column is simply the unbraced length divided by the radius of gyration, 120 inches / 5 inches = 24.
