real numbers are associative and commutative (a mathematical property meaning it doesn't matter in what order you add/subtract them). 1 + 2 = 3 as does 2 +1

Thanks guys! I had a feeling I wasn't just getting lucky each time :D.

(Does gravity have a horizontal component? )

It sure does when you turn your paper theta degrees, haha.

I look forward to posting more and contributing, as I was a lurker before this. You guys are very helpful and damn fast! Again, thanks guys.

[tex]\vec T+ \vec W+\vec f[/tex] (order not important), then choose your axes, then break into components...

[tex] T_x+ W_x+ f_x[/tex] (keep order for bookkeeping)

[tex] T_y+ W_y+f_y[/tex],

then write "0" or the appropriate signed quantities for certain components.
