1. The problem statement, all variables and given/known data
3. The attempt at a solution I don't think this is the correct answer because for some reason I have a constant mg term. Usually I get mgsinθ and from small angle approximations it becomes mgθ, but this time I am getting mgcosθ and from small angle approximations it becomes mg. What am I doing wrong? Or is this correct?

I don't see the distances in your expressions for the moments.
