COSMOS: Complete Online Solutions Manual Organization System Chapter 4, Solution 139. Free-Body Diagram: ΣFx = 0: Bx = 0 ΣM D ( x - axis) = 0: (80 N )( 2.6 m ) − Bz ( 2 m ) = 0 or B = (104.0 N ) k Bz = 104.000 N ΣM D ( z - axis) = 0: Cy ( 4 m ) = 0 Cy = 0 ΣM D ( y - axis) = 0: − Cz ( 4 m ) − (104 N )( 6 m ) + ( 80 N )( 6 m ) = 0 C z = − 36.000 N and C = − ( 36.0 N ) k ΣFy = 0: ΣFz = 0: Dy = 0 Dz − 36 + 104 − 80 = 0, or D = 12.000 N Therefore: D = (12.00 N ) k
