A mechanic uses a crowfoot wrench to loosen a bolt at C. The mechanic holds the socket wrench handle at points A and B and applies forces at these points. Knowing that these forces are equivalent to a force-couple system at C consisting of the force (C = − 40 N)i+ (20 N)k and the couple MC = (40 N ⋅ m)i, determine the forces applied at A and B when Az = 10 N.
