If shaftB is the input and drives gear 2, what is the speed ratio? Ifshaft B rotates at 250 rev/min cw, Find the speed anddirection of shaft A and gears 3 and 4. N2 = 18, N3 = 20, N4= 18, N5 = 22, N6 = 45Question #2 (10 Marks)A simple three-speed transmission is shown. The power flow is as follows:(a) First gear: gear 4 is shifted to mesh with gear 7; power flows through gears 2,5, 7,4.(b)Second ge … Purchase document to see full attachment
