4 A tree is stabilized by two ropes tying at an altitude of 8 feet measured from the foot of the tree as shown by the position O in the figure. It is known that the tension in the rope AB is 100 lb. Let T(AB) and T(AC) be the tension in the rope AB and the rope AC respectively, and X let M be the moment exerting on the tree about an axis through point O due to T(AB) and T(AC). (14, 0, 14) ft (0, 0, 10) ft By using linear combinations of the standard unit vectors i, j, k corresponding to the 3-D rectangular coordinate system x-y-z given in the figure, (a) express the vector form of tension T(AB); (b) express the vector form of tension T(AC) in terms of ||T(AC)|| ; (c) express the vector form of the moment M in terms of ||T(AC)|| ; (d) find ||T(AC)|| when |||| = 1500 lb-ft. (Correct to 1 decimal place.) B A (0, 8, 0) ft
