Calculate the moments M_A and M_B about point A for the forces applied at points

Question

Calculate the moments M_A and M_B about point A for the forces applied at points A and B. Then, determine the resulting couple moment M_{ m R}. Assume that a positive moment produces a counterclockwise rotation whereas a negative moment produces a clockwise rotation.

m Calculate the moments M_A and M_B about point A for the forces applied at points A and B. Then, determine the resulting couple moment M_{rm R}. Assume that a positive moment produces a counterclockwise rotation whereas a negative moment produces a clockwise rotation. r2 = 0.290 m and F = 295 N 0.570

Explanation / Answer

Ma= Fa X R = FaX 0 =0 mb = Fb X R = Fb X 2r1 = 2Fr1 resulting couple moment= 2 F R1 anticlockwise. ie positive
