Replace the loading acting on the beam by 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.

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

Part B

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

?, counted counterclockwise from negative
x
axis

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

Part C

Specify where the force acts, measured from end
A.

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