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 = 9.30 ft, d= 6.40 ft, and h = 4.30 ft. The ball is held in place by three cables anchored at points A, B, and Con the surface of the box. D d point D is the origin of the Cartesian coordinate system, point A is located at (-4.70, -3.80, 2.50) ft, point B is located at (1.70, -3.80, 1.70) ft, and point C is located at (1.70, 5.50,-1.80) ft. If Part A - Determining Cartesian components of force The tension in cable DA has a magnitude of TDA = 10.4 lb. Find the Cartesian components of tension TDA, which is directed from D to A.
