If the 1550-1b boom AB, the 200-lb cage BCD, and the 172-lb man have centers of gravity located at points
G₁, G₂ and G₂, respectively, determine the resultant moment produced by all the weights about point A. (
Figure 1)
Express your answer to three significant figures and include the appropriate units. Enter positive value
if the moment is counterclockwise and negative value if the moment is clockwise.
