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.

ill do it for 100, also this isnt 80 its 40

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
