Learning Goal: To determine Cartesian force components from magnitude and determine position and resultant vectors by summing Cartesian components. As shown, a ball is suspended at point D inside a box with dimensions w = 2.7 ft, d = 12.9 ft , and h = 8.1 ft . The ball is held in place by three cables anchored at points A, B, and C on the surface of the box. https://session.masteringengineering.com/problemAsset/1501037/11/Intro.jpg If point D is the origin of the Cartesian coordinate system, point A is located at (-1.7,-6.0,7.1) , point B is located at (-1.7,6.9,5.1) , and point C is located at (1.0,6.9,-1.0) . Part A - Determining Cartesian components of force The tension in cable DA has a magnitude of T_DA = 760 . Find the Cartesian components of tension T_DA , which is directed from D to A. Part B - Determining an unknown force If the tensions in cables DA and DB are T_DA = 760 and T_DB =1460 , respectively, what is the tension in cable DC?
