I Review Part A Learning Goal: To apply the principle of moments and the principle of transmissibility. As shown, a rope is attached to al = 5.30m high shed that is to be relocated. A man pulls on the end of the rope at point A; the rope is attached to the shed at point B. (Figure 1) As the man pulls on the rope, it creates an angle 0 with the horizontal. The end of the rope is located at x = 3.30m from the shed and y = 2.00m off the ground. The man pulls on the rope with a force of magnitude F = 280N. What is MF., the contribution to the moment about point O made by the x component of the force F at point A? What is ME., the contribution to the moment about point O made by the y component of the force F at point A? What is the total moment M due to the force F about point O? Assume that moments acting counterclockwise about point O are positive whereas moments acting clockwise are negative. Express your answers, separated by commas, to three significant figures. • View Available Hint(s) MF, MF, M = 396,653,1050 N- m Submit Previous Answers v Correct Term 1: Correct answer is shown.

Your answer 1049.34 N · m was either rounded differently or used a different number of significant figures than required for this part. Part B Using the principle of transmissibility, the force F can be slid along its line of action from point A to any other point along its line of action. What points along the line of action of the force F would simplify the calculation of M, the magnitude of the total moment due to the force F about point O?
