A uniform plank XY is supported by two equal 120-N forces at X and Y, as shown. The support at X is then moved to Z (half-way to the plank center). The supporting forces at Y and Z are then: A) F_Y= 240 N, F_Z = 120 N B) F_Y= 200 N, F_Z = 40 N C) F_Y= 40 N, F_Z = 200 N D) F_Y= 80 N, F_Z = 160 N E) F_Y= 160 N, F_Z = 80 N
