1. Homework Statement
A system of cables suspends a crate weighing W = 420 lb. The dimensions in the figure are as follows: h = 20.9 ft, l = 5.70 ft, x = 7.05 ft, theta = 36.0 , and phi = 20.0. Determine TA, TD, and TE, the tensions in cable segments CA, CD, and CE, respectively.
2. Homework Equations
vector F = (magnitude F)(unit vector)
sum F = 0
FCA + FCB + FCD + FCE + FCF + W = 0
3. The Attempt at a Solution
How do I start by finding the coordinates:
C(0,0,0), D(x,0,h), A(?) E(?)
I can't see how to find the correct coordinates A,B,C,D,E,F
