please help me with part a and b ASAP
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 Dinside a box with dimensions w = 2.4 ft, d = 13.0 ft, and k = 7.0 ft. The ball is held in place by three cables anchored at points A By and Con the surface of the box. The ball is held in place by three cables anchored at points A By and Con the surface of the box. If pointais the origin of the Cartesian coordinate system, point A is located at (-1.5, -4.0,5.0) ft, point B is located at (-1.5.9.0,3.4) ft, and point Cis located at (0.9,9, -2.0) ft. Part A Determining Cartesian components of force The tension in cable DA has a magnitude of TDA = G80 lb. Find the Cartesian components of tension TDA which is directed from D to A. Express your answers, separated by commas, to three significant figures. Determining an unknown force If the tensions in cables DA and DB are TDA = 680 lb and TDB = 1500 lb, respectively, what is the tension in cable DC? Express your answer to three significant figures and include the appropriate units.Explanation / Answer
1) Vector DA = A - D = (-1.5i-4.0j+5k) - (0i+0j+0k) unit vector along DA = (-1.5i-4.0j+5k)/6.57 T(DA) = 103.5(-1.5i-4.0j+5k)..........answer 2) to solve for 2nd part, follow same method to get T(DB) now equillibrium, at D net force is = 0 => T(DC) = -[T(DB)+T(DA)]
