Two downward forces act on a light horizontal beam. A 12 N force acts 0.30 m to the left of the pivot. An 8.0 N force acts 0.50 m to the right. What is the resultant moment?
7.6 N m7.6\ \mathrm{N\,m}7.6 Nm anticlockwise.
7.6 N m7.6\ \mathrm{N\,m}7.6 Nm clockwise.
0.40 N m0.40\ \mathrm{N\,m}0.40 Nm anticlockwise.
0.40 N m0.40\ \mathrm{N\,m}0.40 Nm clockwise.
