258 Equivalent horizontal and vertical couples

Problem 258
Replace the system of forces shown in Fig. P-258 by an equivalent force through O and a couple acting through A and B. Solve if the forces of the couple are (a) horizontal and (b) vertical.



Solution 258



The resultant force's magnitude and angle passing through O is correct, but I think it needs to be drawn correctly. The force needs to be drawn steeper than what is shown in the drawing to show the correct angle base on the angles value.
