from the figure we can write
as the net forces in the x direction are zero so we get
as the net forces in the y direction arezero so we get
therefore the resultant force will be 84.9N
b) the weight of the traffic light is directeddownwards and the force is directed upwards
as the traffic light is at equilibrium positionwe get the same force as the the weight of the lights as
W = 84.9 N
