Replace the loading acting on the beam with a single resultant force. Take F1 = 420 N , F2 = 300 N , F3 = 740 N .
(Figure 1)

Part A

Determine the magnitude of the resultant force.

Part B

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

 counted counterclockwise from the negative x-axis

Part C

Specify where the force acts, measured from end A.
