5. Two C310x45 channels are latticed together so they have equal moments of inertia about the principal axes. Determine the minimum length of column having this section, assuming pinned ends, E = 200 GPa, and a proportional limit of 240 MPa. What safe load will the column carry for the length of 12 m with a factor of safety of 2.5? For C310x45, take I = 67.3×106 m4 Ans L = 9.89 m, F = 738 kN 6. Repeat problem 5 assuming that one end is fixed and the other hinged.
