Understanding the Impact of Shaft Diameter Changes on Torque

[Darnell123]

hi,

could anyone explain to me how a change in a shaft diameter affect the Torque.

let's say D1/D2=1.5, should i assume Torque2 = Torque1 / 1.5 ?

thanks for your help

You will have to clarify the question. Is this a shaft under a given load that has an abrupt diameter change at some point along its length? Or are you saying that if one shaft is fatter than the other, how much more torque can it support? Or are you asking something else?

indeed it is one shaft having an abrubt change in diameter along its lenght.
