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

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.

scientific laws are the result of testing theories and proving them to be facts.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
