A gearing system as shown in Figure Q3.2 is used to reduce the rotational speed 3000 rpm of the motor to 300 rpm at the output shaft.If diametral pitch of the gear is P = 10 in ¹ is used for all the gears (G2 to G5) with 20° pressure angle. The number of teeth for G2 is 30T, G3 is 60T and G5 is 200T. The torque requirement of the output is 2500 lb.in and the output shaft rotates in counter clock wise direction. Based on this information, answer the following questions: (i) (ii) (iii) Calculate the train value of the gearing system and the number of teeth of gear G4. Draw the free body diagram and their magnitude of gear G3, G4 and G5. Calculate the power of motor in horsepower (hp) and the torque of the motor @3000 rpm. (iv) If an idler gear is added in between gear G4 and G5, does the diameter of the gear will have the effect on the torque of the output and state the reason why.
