- A couple moment of magnitude \( M=80 \mathrm{lb} \)-in. and the three forces shown are applied to an angle bracket. (a) Replace the system of forces and the couple with an equivalent force-couple system at B. (b) Replace the equivalent force-couple system with a single resultant force along line \( A B \) and specify it's distance from point \( B \).
