Part A Replace the loading system acting on the beam by an equivalent resultant force and couple moment at point O Suppose that F1 = 550 N , F2 = 200 N , and Determine the magnitude of the resultant force. M = 300 N . m (Figure 1) Express your answer to three significant figures and include the appropriate units. FR = Value Units Submit Request Answer Part B Determine the angle between the resultant force and the x axis. Express your answer using three significant figures It vec 0 = o, measured counterclockwise from the negative x axis Submit Request Answer Figure Part C Determine the equivalent resultant couple moment about point O Express your answer to three significant figures and include the appropriate units. Enter positive value if the m counterclockwise and negative value if the moment is clockwise. 30 0.2 m 1.5 m 2 m 1.5 m- (MR)o= Value UnitsPart A The building slab is subjected to four parallel column loadings.
