(3) Working with Couples (Non-Planar) (5 pts) Six forces are applied to a bent bar as shown in Figure 3. (a) Identify any force couples and the axis about Which they act. (Hint: remember that the couple moment produced by a couple is independent of the moment center, so your answer will be the same whether you choose A, B, 0 or any other point.
