Answer
The maximum weight of the chandelier is 1170N
Work Step by Step
To find the max weight of the chandelier, we will set the cords to their maximum allowable tension given, 1660N, and then sum the forces vertically. Let W be the weight of the chandelier. Let T be the tension in the cord. Therefore;
$(\uparrow +) \sum \overrightarrow{F}_{y} =0 $
$-W+sin(45^{\circ})*T=0$
$W=sin(45^{\circ})*T$
$W=sin(45^{\circ})*1660N$
$W\approx1170N$
