Question

As shown, a submarine hatch door is to be opened by applying two oppositely oriented forces of equal magnitude F=205N at points A and B on the hatch door wheel. The radii of the wheel's outer and inner rings are R1= 0.330m and R2 = 0.130m , respectively. Calculate the moments and about point D for the forces applied at points A and B. Then, determine the resulting couple moment . 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.
