I think you need the lengths of the two bars.

The bars are 500mm long each. How do I calculate the torque?

Torque = force times length.

So, what do you think you should use for length and force?

You sure the bars are of equal length? Looks like bar 1 is longer than bar 2.

No, since that's the formula for angular momentum, not torque.

You never answered my question: are you sure the masses are of equal length?

Yes. Both the masses are of equal length.

OK, (though I'm still wondering why the drawing shows them as clearly of different lengths).

How about writing an expression for the torque about the axis of rotation as a function of angular position? You can call zero angle at any position you like.

Take one bar at a time. What's the torque gravity applies to one of the bars as a function of its angular position?
