Find expressions for all support reaction forces in the plane frame with load 2P applied at C, as shown in the figure. Joint A is sliding support, joint D is pinned, and joint F is roller support. Assume that member AC is a flat prismatic bar of length L, width b, and thickness t. Beam ABC is pinned to column DBF at mid-height (point B). Column DBF has constant thickness t and width b for DB but width 2b for BF. Consider load 2P at C only; neglect the weights of all members. The modulus of elasticity E is the same for both members. Select reaction RF as the redundant.
