Determine the maximum mass of the lamp that the cord system can support so that no single cord develops a tension exceeding 350 N
The Attempt at a Solution
F(x)=0; F(ED)cos30 - F(CD)= 0
F(y)=0; F(ED)sin30 - W
F(X)=0; 1.73205W - F(AC)(3/5) - F(CD)cos45 = 0
F(y)=0; F(AC)(4/5) - F(BC)sin45 = 0
This is where I start getting confused. With all the substitutions.
