Problem 9: The following steel structure is subjected at point A along the y axis, where there is also a spherical (ball) hinge, which constraints translations along x, y, and z at A, and there is a plane hinge at C. This plane hinge is contained in the x-z plane, which means it constraints translations along the x and z-axes. The force of 500 N at F is also contained in the x-z plane, forming 45° with the x-axis. The...
