1. In a room with a ceiling height of 2.6 meter, a 2.5 meter plank is supported by a cable attached to the ceiling and box, as shown in the figure. If the cable is 0.945 meters in length and the height of the box is 0.8 meters, (a) determine the weight of the plank when cable A exerts a force of 100 N. (b) Determine the vertical force (perpendicular to the horizontal ground) exerted by the Box on the plank. Note: Neglect the thickness of the plank A P B
