Problem is here http://engineeringhomework.net/statics/hw1p19.html" [Broken] I understand that Tr=T1+T2, but the different axis is throwing me off.

hi bbarke00! :smile:

to find the component of F in a particular direction,

always multiply F by cos of the angle from that direction

(the only time you use sin is when you're given an angle θ which is 90° minus the angle you want … then it's still cos, but it's cos(90° - θ) which of course is sinθ :wink:)

show us what you get :smile:
