The net force is the sum of all forces and it acts on the center of mass.
If the two forces have the same magnitude but opposite directions the sum of both forces is zero.
Torque = Force * Perpendicular distance.
180 Nm = F * 1.6.
F* 1.6 = 180.
F = 180/1.6 Use your calculator.
F = 112.5.
Force is 112.5 N. That's it.
