Force | Perp. distance(m) | Moment (Nm) |
8 N at \displaystyle D | 2 | \displaystyle -8\times 2=-16 |
20 N at \displaystyle D | 0 | \displaystyle 20\times 0=0 |
18 N at \displaystyle C | 5 | \displaystyle -18\times 5=-90 |
16 N at \displaystyle C | 2 | \displaystyle 16\times 2=32 |
24 N at \displaystyle B | 0 | \displaystyle 24\times 0=0 |
Total Moment | \displaystyle -16+0-90+32+0=-74\text{ Nm} |
