(48 Points) Consider the structure shown in Fig 5. Bar \( A B \) is buried in the wall. Bar \( A B \) is 3 meters long. A sphere with radius \( 1 \mathrm{~m} \) is centered at \( \mathrm{B} \). \( \mathrm{A} \) is \( (0,0,0), \mathrm{B} \) is \( (0,3,0), \mathrm{C} \) is \( (0,3,-1) \), D is \( (-.1,3.7, .7), \mathrm{E} \) is \( (1,2,3) \). A force of \( -100 \mathrm{j} \) is applied to \( C \). The force applied at point \( D \) has a magnitude of \( 100 \mathrm{~N} \). Find the moment about line \( \mathrm{AE} \). Moment \( \mathrm{About} \mathrm{AB}= \)
