I think I understand now: We have the length of the rope so the radius of the rope can be described as the horizontal component of the length of the rope. Thanks for your help, it was hard for me to see.
Perhaps I'm having difficulty understanding what is being described. The rope is at an angle twirling some object in a horizontal circle. I understand why the tension would need to be broken down into its components. But it seems that the radius of the horizontal circle is purely horizontal...
I'm having difficulty understanding why the radius is not represented by r, but Lcostheta , isn't the entire rope in the horizontal direction? There is something I'm missing. Thanks. (Hopefully I posted this correctly.)
