Question

Which of the following gives the moment MD about point D of the tensile force TBA exerted by the wire at point B? Note that rB/D = (4i - 6k) m and TBA = (-8i + 6j + 4k) kN and that MD = rB/D x TBA. 
a. (36.0i + 32.0j + 24.0k) kN-m
b. (48.0i + 24.0j + 16.0k) kN-m
c. (-36.0i - 32.0j - 24.0k) kN-m
d. (16.0i - 12.0j -8.0k) kN-m
