As shown, a 2.7-lblb ball is suspended at point D inside a box with dimensions w=8.90 ft, ft, d=6.50ft . The ball is held in place by three cables anchored at points A, B, and C on the surface of the box. point D is the origin of the Cartesian coordinate system, point A is located at (−4.60,−3.60,2.80)ft, point B is located at (1.90,−3.60,1.90) ft, and point C is located at (1.90,5.30,−1.70) ft. 1.The tension in cable DA has a magnitude of TDA lb. Find the Cartesian components of tension TDA , which is directed from D to A. 2.If the tensions in cables DA and DB are TDA =7.23 lb and TDB =5.20 lb, respectively, what is the tension in cable DC?

As shown, a 2.7-lblb ball is suspended at point D inside a box with dimensions w=8.90 ft, ft, d=6.50ft . The ball is held in place by three cables anchored at points A, B, and C on the surface of the box. point D is the origin of the Cartesian coordinate system, point A is located at (−4.60,−3.60,2.80)ft, point B is located at (1.90,−3.60,1.90) ft, and point C is located at (1.90,5.30,−1.70) ft.
1.The tension in cable DA has a magnitude of TDA lb. Find the Cartesian components of tension TDA , which is directed from D to A.
2.If the tensions in cables DA and DB are TDA =7.23 lb and TDB =5.20 lb, respectively, what is the tension in cable DC?
