(a) As shown in Figure Q2(a), the teeth number of gear A, B, C, and D are 30, 36, 18, and 54, respectively. Gear B and C are fixed on the same shaft. The angular velocity of gear A is 1440 rev/min. Find the angular velocity of gear D. (6 marks) (b) In the gear box shown in Figure Q2(b), the gear ratio A = the teeth number of gears B, C, and D. 12 A (a) Gear pairs. ܡܢܙ A B Gear A has 30 teeth.
