Replace the force system acting on the beam by an equivalent resultant force, and specify its point of application on the beam measured from point $O($Figure $1).$ Take $F_1=8lb,F_2=16lb,$ and $F_3=48lb.$

Part A

Determine the magnitude of the resultant force.

Express your answer in pounds to three significant figures.
