The manufacturer of an automobile is considering the two designs shown for the vehicle's lug nut wrench. Forces FA, FC QA, and QCare applied by the user to the wrench; these forces are perpendicular to plane ABCD and are to be couples. 40 mm FA 40 mm 25 mm 25 mm 25 mm TFC If FA = QA = 130 N, determine Fc and QC, and for each wrench, determine the moment of the couple. (Include a minus sign if necessary.) The value of Fcis N. The value of QC is N. The moment of the couple of wrench (a) is ( N-mm) The moment of the couple of wrench (b) is ( | + j) N-mm.
