Review Learning Goal: To demonstrate the consistency of the principle of moments by calculating a moment using the scalar and vector methods and comparing the results. As shown, a curved member is fixed at point O. The radius of the member is r = 3.80 ft and F has magnitude F = 520 lb. (Figure 1) Part A - Calculating the moment about O using the scalar method In two dimensions, the moment of a force can be calculated using the scalar method, Mo= Fd, where F is the magnitude of the force and d is the perpendicular distance from the line of force to the point where the moment is being considered. Using the scalar method, calculate the moment about O due to F. Express your answer to three significant figures and include the appropriate units.

We can use the scalar method to individually compute the contributions to the moment from the components. (Figure 2)What is the moment about O due to only the x component of F? Express your answer to three significant figures and include the appropriate units.
