need to know the part A,B,C solutions ways.
Part A As shown, a submarine hatch door is to be opened by applying two oppositely oriented forces of equal magnitude F = 130 N at points A and B on the hatch door wheel. The radii of the wheel's inner and outer rings are ri = 0.550 m and r2 = 0.130 m, respectively. (Figure 1) Calculate the moments MA and MB about point 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. Learning Goal: 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.

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) D MA,MB, MR = 0.000,143,143 N.m B F Submit Previous Answers Correct The two methods of calculating the couple moment in Parts A and B are equivalent and produce the same resultant moment magnitude MR Because it only requires one calculation, Part B's method is simpler. Choosing a reference point along one force's line of action reduces the moment arm to zero. Therefore, when calculating a couple moment, choose the reference point that most simplifies the calculation. Figure 2 of 2 > Part C The same couple moment of 143 Nm is required to open the hatch door, independent of where the couple's forces are applied. If the forces are applied at points C and D, what force magnitude F is required to open the hatch door? (Figure 2) Express your answer numerically in newtons to three significant figures.
