Understanding the Impact of Shaft Diameter Changes on Torque

Click For Summary

Discussion Overview

The discussion centers around the effects of changes in shaft diameter on torque, specifically in the context of a single shaft with an abrupt diameter change along its length. Participants seek to clarify the relationship between diameter and torque under these conditions.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant asks how a change in shaft diameter affects torque, proposing a relationship based on the ratio of diameters.
  • Another participant requests clarification on whether the question pertains to a shaft under load with a diameter change or if it concerns the torque capacity of a thicker shaft compared to a thinner one.
  • A subsequent reply confirms that the scenario involves a single shaft with an abrupt diameter change.
  • Another participant emphasizes the need for a clear problem statement, including all variables and relevant equations, and requests an attempt at a solution.

Areas of Agreement / Disagreement

Participants have not reached a consensus, as there are differing interpretations of the initial question and the necessary details required to address it.

Contextual Notes

Limitations include the lack of specific variables, known data, and relevant equations that could guide the discussion. The relationship between shaft diameter and torque remains unspecified and unresolved.

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.

Please state the problem statement, noting all variables and given/known data; list the relevant equations you think you might need to solve the problem; and show some attempt at a solution.
