# Three-dimensional vectors and force systems

Full disclosure: this is a homework problem. However, I find myself stuck in the middle. The problem is below

As shown, a system of cables suspends a crate weighing W = 350 . (Part C 1 figure) The dimensions in the figure are as follows: h= 22.2 , l = 4.20 , x = 9.50 , theta = 40.0, and phi = 16.0. Determine TA, TD, and TE, the tensions in cable segments CA, CD, and CE, respectively.

I already found that TA = 406, i still need to find TD and TE. I know that CE = CF and that I need to find TD and TE through the Z forces and that the Y forces in these two should equate but I'm not sure about that either.

A push in the right direction would be a huge help.

Do add figures, we don't even know about T, A, B, and blahblahs. – user21436 Feb 5 '12 at 7:29
With many forces and tensions playing a role are you sure this wouldn't be better received on a physics forum? Do add the figure. Kinda pointless otherwise :-) – Jyrki Lahtonen Feb 5 '12 at 7:56
Thanks much for the suggestions, I'm new to math.stackexchange. Apparently I need 10 rep to post an image, but here is a link in case someone can edit. i.imgur.com/Q6foU.jpg – Evan Chipps Feb 5 '12 at 8:24
Also, I wasn't aware of the Physics.StackExchange site. Can someone with rights move my question over, or should I crosspost? – Evan Chipps Feb 5 '12 at 8:26
