Answer by selecting the correct options from the following multichoice selection. ப 4m B A C D 3m 3 m Figure Q17 FL 12 kN E 16 KN A. We should resolve forces in the horizontal direction to easily identify the internal force DF. B. The solution to the problem is found to be -16 kN (C). C. We should resolve forces in the vertical direction to first identify the internal force DF. D. We should use Method of Joints at node F to find the internal force in member DF. E. We should Method of Sections by cutting through members DF, DE and CE. F. The starting point to solve this problem is to find all reactions at nodes A and B as they will be required for DF calculations. G. The solution to the problem is found to be 16 kN (T). H. The most appropriate method to find DF use is Method of Joints. I. The most appropriate method to use is Method of Sections. J. A good starting point to solve this problem is to find the horizontal reaction at node B but this is not required to the internal force
