Question:

The chandelier is supported by three chains which are concurrent at point O. If the force in each chain has magnitude F, express each force as a Cartesian vector and determine the magnitude and coordinate direction angles of the resultant force.

Given:
F = 60 lb
a = 6 ft
b = 4 ft
θ1 = 120 deg
θ2 = 120 deg

The chandelier is coordinate direction angles of the resultant
