Figure

Part C

Specify where the force acts, measured from end $A.$

Express your answer using three significant figures.

$x=$

ft to the right from end $A.$ Replace the three forces acting on the shaft by a single

resultant force. Suppose that $F_1=550lb,$

$F_2=400lb,$ and $F_3=390lb.($Figure $1)$

Part A

Determine the magnitude of the resultant force.

Express your answer to three significant figures and include the appropriate units.

$F_R=$

Units

Part B

Determine the angle between the resultant force and the $x$ axis.

Express your answer using three significant figures.
