I Review Express your answer numerically in Newton-meters to three significant figures. • View Available Hint(s) Learning Goal: To understand the concept of moment of a force and how to calculate it using a scalar formulation. MR, = -4.54 N·m The magnitude of the moment of a force with a magnitude F around a point O is defined as follows: Submit Previous Answers Мо — Fd where d is the force's moment arm. The moment arm is the v Correct perpendicular distance from the axis at point O to the force's line of action. Part C As shown, a server at a restaurant is carrying a tray that has a glass of water resting on it. (Figure 3) The glass and tray exert a force with magnitude Fi = 28.5 N on the server's hand. If l1 = 0.390 m , l2 = 0.290 m , l3 = 0.130 m, ai = 155 °, and 2 = 120 °, what is the moment of force about the shoulder joint at point A? Assume that moments acting in the counterclockwise direction about point A are positive whereas moments acting in the clockwise direction are negative.
