The door is partially open, making an angle of 20° with y-axis, as shown below. Total length of door is 52 inches. Distance from O to A is 34 inches (this distance is not parallel to y-axis) a) Express force F (magnitude F = 150 lb), from A to B, as a Cartesian vector. b) Find the magnitude of the moment of force F about the line from O to D. Express this moment as a Cartesian vector.
