statics
Replace the loading acting on the post by an equivalent resultant force and couple moment at point \( P \) (Figure 1). Suppose that \( F_{1}=36 \mathrm{lb}, F_{2}=72 \mathrm{lb} \), and \( F_{3}=48 \mathrm{lb} \).
Determine the magnitude of the equivalent resultant force. Express your answer in pounds to three significant figures. Part B Determine the angle between the resultant force and the \( x \) axis. Express your answer in degrees to three significant figures.
Determine the equivalent resultant couple moment at point \( P \). Express your answer in pound-feet to three significant figures. Enter positive value if the moment is counterclockwise and negative value if the moment is clockwise.
