Determine the moment about the origin O of the force F= -21-3j+5k that acts at point A. Assume that the position vector of A is F = 4î+63 - 10k. Also, determine the equivalent force (if possible) that could be applied at F = 41+33 +5k that would induce the same effect. If it is not possible, show/explain why not.
