Question $2$Replace the force system acting on the frame by an equivalent resultant force, and specify where the resultant's line of action intersects member AB $($Figure $1).$ Suppose thatF$1=15$ lb$,$ F$2=35$ lb$,$ F$3=45$ lb$,$ and F$,=25$ lb$.$

Part ADetermine the magnitude of the resultant force. Express your answer in pounds to three significant figuresF$\_$r $=($Units lb$)$

Part BDetermine the angle between the resultant force and the axis. Express your answer in degrees to

three significant figures.Angle $=($Units degrees$)$Part CDetermine the magnitude of the moment about point A$.$ Express your answer in per feet to three significant figures $.$M$\_$A $=($Units lbft$)$

Part DSpecify where the resultant's line of action intersects member AB$,$ measured from point A Express your answer in feet to three significant figures.y$=$ ft above A$*$ First, draw FBD $($correct FBD earns up to $30\%$ credit$)*$ Second, build equations of equilibrium $($correct equations earns additional $40\%)*$ Third, solve the equations for unknows of interest $($correct solutions earns additional $30\%)$Please make sure you write these important components
