Learning Goal: To analyze an ideal column with pin supports, determine the critical load and critical stress on the column, and determine the maximum applicable distributed load on the system. As shown, beam BC is supported by columns AB and CD and has length Lw=20.0 ft. Both columns have the cross section shown and have lengths of L₁ = 17.5 ft. Let a = 6.00 in, b = 1.50 in, c = 12.00 in, and d = 3.00 in. Assume E = 28000 ksi. Column AB is pinned at both ends. (Figure 1) Figure B W L. 1 of 1 I ▼ Part A Critical load for column AB Determine the critical load, Per, that column AB can support.
