15. Two L102 × 76 × 9.5 structural steel angles (look for cross-sectional properties) are used as a compression member that is 4.5-m long. The angles are separated at intervals by spacer blocks and connected by bolts (as shown in Fig. 15), which ensure that the double-angle shape acts as a unified structural member. Assume pinned connections at each end of the column and use E = 200 GPa for the steel. Determine the Euler buckling load for the double-angle column if the spacer block thickness is (a) 5 mm or (b) 20 mm. spacer block Double Angles L102-76x9.5 Long legs back-to-back 76 mm 76 mm spacer thickness Fig. 15
