Answer:
E. -23.254 N m
Explanation:
We can represent the situation with the following diagram
Then, the net torque is equal to the torque exerted by each force where it is positive if the rotation is counterclockwise and negative otherwise. Since the torque is equal to the force times the distance to the pivot, we get:
[tex]\begin{gathered} \tau_{net}=-(4\text{ N\rparen\lparen2.2 m\rparen - \lparen11 N\rparen\lparen1.4 m\rparen + \lparen0.43 N\rparen\lparen2.2 m\rparen} \\ \tau_{net}=-8.8\text{ Nm -15.4 Nm + 0.946 Nm} \\ \tau_{net}=-23.254 \end{gathered}[/tex]
Therefore, the answer is
E. -23.254 N m
