As shown, a submarine hatch door is to be opened by applying two oppositely oriented forces of equal magnitude F = 310 N at points A and B on the hatch door wheel. The radii of the wheel's inner and outer rings are ri = 0.500 m and r2 = 0.250 m respectively. (Figure 1) Calculate the moments MA and Mg about point D for the forces applied at points A and B. Then, determine the resulting couple moment MR. Assume that a positive moment produces a counterclockwise rotation whereas a negative moment produces a clockwise rotation. Express your answers numerically in newton-meters to three significant figures separated by commas. • View Available Hint(s) MA MB, MR = 233,77.5,310 N m Submit Previous Answers Correct • Part B Calculate the moments MĄ and MB about point A for the forces applied at points A and B.

Learning Goal: As shown, a submarine hatch door is to be opened by applying two oppositely oriented forces of equal magnitude F = 310N at points A and B on the hatch door wheel. The radii of the wheel's inner and outer rings are ri = 0.500 m and r2 = 0.250 m, respectively. (Figure 1) Calculate the moments MĄ and MB about point D for the forces applied at points A and B. Then, determine the resulting couple moment MR. Assume that a positive moment produces a counterclockwise rotation whereas a negative moment produces a clockwise rotation. To be able to calculate couple moments. A couple is defined as two parallel forces, separated by a distance, that have equal magnitudes but opposite directions. A couple only produces a rotation in a specified direction. The moment produced by a couple is called a couple moment. Express your answers numerically in newton-meters to three significant figures separated by commas. • View Available Hint(s) MA MB, MR = 233,77.5,310 N. m Submit Previous Answers Correct Figure 1 of 1 Part B F A Calculate the moments MĄ and MB about point A for the forces applied at points A and B.
