Problem 4.114 Replace the force system by an equivalent resultant force and couple moment at point O (Figure 1). Set $F_1 = 15$ lb and $F_2 = 10$ lb. Part A Determine the magnitude of the resultant force. Express your answer in pounds to three significant figures. $F_R =$ lb Part B Determine the angle between the resultant force and the z axis. Express your answer in degrees to three significant figures. $\theta =$ °, measured counterclockwise from the positive z axis Part C Determine the equivalent resultant couple moment about point O. Express your answer in pound-inches to three significant figures. Assume the positive direction is counterclockwise. $(M_R)_O =$ lb-in.
