The elements of a wall-mounted swing-away stool are shown in the figure. The hinge pin P fits loosely through the frame tube, and the frame tube has a slight clearance between the supports A and B. Determine the reactions on the fram tube at A and B associated with the weight L of an 80 kg person. Also, calculate the changes in the horizontal reactions at C and D due to the same load L.
