I'm trying to setup a free body diagram for this problem, and I'm not even sure where to start with the angles. That is basically my question, when do I use cos and when do I use sin. It has never made sense...
Links to tutorials, or an explanation on setting up a free body diagram would be enormously helpful.
Thanks!
