Beam ACB has a sliding support at A and is supported at C by a pinned-end steel column with square cross section (E 5 200 GPa, b 5 40 mm) and height L 5 3.75 m. The column must resist a load Q at B with a factor of safety of 2.0 with respect to the critical load. The max-imum permissible value of Q is approximately:
(A) 10.5 kN
(B) 11.8 kN
(C) 13.2 kN
(D) 15.0 kN
