Answer:
240 Nm
Step-by-step explanation:
The clockwise torque is the torque determined only by the force that makes the lever rotating clockwise: therefore, the force of 80 N on the right.
The torque produced by this force is given by:
![\tau = F d](https://img.qammunity.org/2020/formulas/physics/middle-school/kzu7cfumvqnda5t3sgrmtyvh2sbbwcdylf.png)
where
F is the magnitude of the force
d is the arm
For the force of 80 N on the right,
F = 80 N
d = 3 m (distance from the pivot)
So, the clockwise moment is
![\tau = (80)(3)=240 Nm](https://img.qammunity.org/2020/formulas/physics/middle-school/6dj83asf75u3vqtrx85f6ex3562jng1yct.png)
