I need to show that $\displaystyle \omega$ and $\displaystyle \theta$ are related by the following equation: $\displaystyle (a+h \sin \theta){\omega}^2=g \tan \theta$ by creating a force diagram of the situation shown in the attachment. Any help at all would be greatly appreciated Attached Thumbnails
