The shape does not matter. Your diagram is correct.

Thanks. So what if the moment arm is attached to an axel (depicted in the drawing as a dot) while at the same time being pulled downward by gravity. How does that downward, rotational movement affect the torque at the axel. Thanks.

I'm not seeing how that is a different scenario from that depicted in your original diagram.
Can you explain more clearly what this second scenario is?

A question: how is it arranged that the outer part of the lever remains horizontal as the inner part rotates?
