I am in introductory physics, and have just been introduced to the topic of toque. For forces in translational motion, I know that we idealize objects to be point particles. However, when it comes to torque, we don't deal with point particles, but with "lever arms." I guess essentially my question is, what does the typical free-body diagram look like for a torque problem? For regular forces the FBD is just a point with arrows.
