In this problem, we will compare and contrast the performance of the two lug nut wrench designs de- picted in the figure below. A user applies forces FA and Fc directed perpendicular to the plane ABCD of the lug nut wrench in figure (a). Forces QA and Qc are directed perpendicular to the plane ABCD of the lug but wrench in figure (b). The pair of forces in each case constitute force couples. 25 mm 40 mm (a) 1 40 mm 12c 25 mm D 25 mm (b) a Assuming FA = QA = 120 N, compute Fc and Qc, and the moment of each corresponding couple. b Independent measurements conducted by an auto manufacturer have shown that a moment of 8000 Nm about the x-axis at point D is required to loosen the lug nut. Based on this knowledge, compute the forces FA, Fc required to loosen the nut using the lug wrench in figure (a), and QA, Qc required to loosen the nut using the lug wrench in figure (b).
