Part A Replace the loading by an equivalent resultant force and couple moment acting at point O. Suppose that w1 = 9 kN/m and w2 = 4.5 kN/m . (Figure 1) Determine the equivalent resultant force. Express your answer to three significant figures and include the appropriate units. Enter positive value if the force is upward and negative value if the force is downward. ?
