Thank you for the video! I have a homework problem that is similar to this one with a few extra additives and I finally understand enough to solve it

for calculating angle of twist of B, how do we decide which torque to consider? (why was the 15, 000 kN mm not included?)

What if the gears have two different values ?
Like instead of 50mm and 100mm we have 80mm and 240mm. Do i still multiply the bigger one by 2?
