Question

If the tensions in cables DA and DB are TDA=8.49 lb and TDB=5.64 lb, respectively, what is the tension in cable DC?
Express your answer to three significant figures and include the appropriate units.
Learning Goal: To determine Cartesian force components from magnitude and determine position and resultant vectors by summing Cartesian components. As shown, a 2.9-lb ball is suspended at point D inside a box with dimensions w = 8.70 ft, d = 6.60 ft. and h = 4.50 ft. The ball is held in place by three cables anchored at points A, B, and C on the surface of the box. If point D is the origin of the Cartesian coordinate system, point A is located at (-4.70, -3.80,2.90) ft. point B is located at (1.90, -3.80,1.90) ft. and point C is located at (1.90,4.90,-1.60) ft.
