1. The problem statement, all variables and given/known data What are the directions of my forces acting on mass m with respect to my "m" frame (see attachment)? 2. Relevant equations some trig and transformations maybe... 3. The attempt at a solution I know I only have tension, weight, and a normal force acting on my particle but I cannot tell their directions. I want to have tension acting in the -Im direction, and by the way I have drawn that frame (Im, Jm, Km) it looks as if the force from gravity will be acting in the -Jm direction. However, I am confusing myself whether or not it actually is. If that's the case then I'm left with the normal force which acts in the Jm and Ii direction, correct? I can then translate Ii into m frame terms if so.
