Atension cable (abc) is used to support a boat lifted from a dock. the cable is attached to a davit at b which is rigidly connected at d. given the following: tension in cable abc = 60 n x a = -17.5 m y a = 7 m z a = -10.5 m x b = -17.5 m y b = 17 m z b = -10.5 m x c = 0 m y c = 0 m z c = 10.5 m x d = 0 m y d = 0 m z d = 0 m matlab input: x_a = -17.5 y_a = 7 z_a = -10.5 x_b = -17.5 y_b = 17 z_b = -10.5 x_c = 0 y_c = 0 z_c = 10.5 x_d = 0 y_d = 0 z_d = 0 determine the moment at d due to the resultant force acting at b. g
