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

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
