Technician A says that in order for a planetary gearset to change the ratio and transmit torque, there must be an input and a reaction member. Technician B says that the turbine shaft is the primary input to the transmission. Which technician is correct? a. Tech Ab. Tech Bc. Both A and Bd. Neither A nor B

Answer: C both A and B

Explanation:

Transmission : This simply implies the difference in rotation speed between the input shaft and output shaft. Note that higher gear ratios are used to transfer more torque, of which lower ratios trade torque is in favor of speed. Technician A was right

The primary functions of the transmission includes transmitting of the engines crankshaft into a more usable rotational speed and to multiply the torque of the engine's output. Hence,

Technician B was also right.
