Find Ax, Ay, Ex and Pmax

(a) Determine the reactions at A and E if P = 780 N. The reactions are positive if to the right or up, negative if to the left or down. (b) What is the maximum value which P may have for static equilibrium? Neglect the weight of the structure compared with the applied loads. 29 3860 N B 3.7 m E D 6.5 m 6.5 m D Answers: (a) If P = 780 N, AX = i N N
