(2) The uniform door panel weighs 60 lb and is supported by hinges at A and B. A strut C is used to prevent the door from swinging when a horizontal force P = 50 lb is applied perpendicular to the door panel as shown. Determine the compression C in the strut and the magnitudes of the reaction forces normal to the hinge axis at A and B. Ans: C = 100 lb, An = 38.0 lb, B = 45.5 lb 40" 8" 48" 40" x 30" 8 8 A
