Structure ABCD is rigid and is built-in at point A. Point A is at the origin of the coordinate system and points B and D have coordinates of (22, 30, 54) in and (Dx, 46, -1) in, respectively. Point C is at the midpoint of the straight bar AB. The force P applied to point D of the structure has 500 lb magnitude and directions angles 0x = 95°, 0y = 30°, and 0₂ = 60.5°. A. Determine the unknown coordinate, Dx, so that portion CD of the structure is perpendicular to bar AB. Dx = B. Determine the unit vector that is perpendicular to both AC and CD such that the vector has a negative x component. Unit Vector = + ĵ + C. Determine the scalar component of the force in the direction parallel to CD, in lb: D. Determine the scalar component of the force in the direction normal to CD, in lb: 2 C B D y k
