4.) The uniform 4-kg rod AB is supported by a ball-and-socket joint at A and by the cord CG that is attached to the midpoint G of the rod as shown in the figure. The rod leans against a frictionless vertical wall at B. Determine the reactions at A and B and the tension in cord CG. [Answer: T = 20.8 N, Ax= -14.7 N (down), Ay= 29.4 N, Az 11.0 N, B= 29.0 N, where the positive answer indicate the reaction goes in the positive direction of the respective axis and vice versa] Hints: Note the given mass from which you need to calculate weight. IF G is is the midpoint of the rod, then the x, y, z coordinates of that point can be taken to be half the x,y,z components of the position vector FAB 150 mm, B 400 mm 0 150 mm 600 m G
