PE# 2 A 140 kN force is applied to the box below at A along theline from A to B.
a) Use the vector cross product to find the moment of the 140 kNforce about point D. (answer in
vector form)
b) Now, use the rectangular components of the 140 kN force to findits moment components about
the x, y and z axes. (answers will be scalar quantities)
