7. A hatch door is rusted shut at the hinges. The hinges are aligned with the x-axis. (a) To open the door, a person pulls on a rope attached to the hatch door, as shown, with 300N of force. What is the moment generated about the axis of the hinges if the rope is attached to the corner of the hatch at point A? The endpoint of the rope C is located at (0.5, 0, 0.8) m. 30ON C A 1m X 1m (b) What would be the magnitude of the force required to generate the same moment magnitude about the x-axis as in part (a) if the rope was attached at a point B, as shown? The endpoint of the rope C remains at (0.5, 0, 0.8) m. 0.5m y B Im X 1m
