Question

Problem (20 pts) Structure ABCD is supported by a collar at D that can rotate and slide along bar EF, which is fixed and is 2 m frictionless. Structure ABCD makes contact with smooth surfaces at A and C where the normal direction n to the surface at A lies in a plane that is parallel to the xy plane. Force P is parallel to the y axis. If P-10 kN, determine the reactions at A, C, and D P E 4 m 2 m 2 300
