(6) The 7-m uniform bar AB weighs 1.8 kN with its center of gravity at G. The bar is supported by a ball-and-socket joint at A on the floor, and the ball end B rests against the corner of two smooth vertical walls as shown. For the horizontal 1.6 kN force applied at G along the x-axis direction, determine (a) the normal forces from the walls at B (b) the reaction at support A. Ans: (a) NBx=1.4 kN, NB = 1.8 kN (b) A 2.55 kN N B 7 m G 1.6 kN A 2 m 6 m
