Shouldn't it be Pdc = 22kN rather than Pcd? I mean the 22kN force arrow is pointing towards C? Because Pdc means the P from D to C no?

View attachment 81257Pcd is the force of c on d. Pdc is the force of d on c. Free body diagram of cut section 3-3 to D is shown. You can draw FBD of cut section 3-3 to A to get Pdc. Or use Newton 3.
