Calculating Torque and Strength of Materials

Click For Summary

Discussion Overview

The discussion revolves around calculating torque and the strength of materials, focusing on a specific problem presented by a participant. The scope includes homework-related inquiries and technical calculations.

Discussion Character

  • Homework-related, Technical explanation

Main Points Raised

  • One participant shares their work on a torque calculation problem and seeks feedback on its correctness.
  • Another participant points out that the links to the images of the problem and work do not function properly.
  • After fixing the links, the original poster expresses uncertainty about their progress and wishes for a way to verify their solutions.
  • A different participant suggests checking the torque calculation and provides an equation for torque in terms of power and a rule of thumb based on distortion energy.
  • This participant acknowledges that the original poster seems to have the right idea but does not confirm the correctness of their calculations.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the correctness of the original poster's calculations, and uncertainty remains regarding the accuracy of the torque calculation.

Contextual Notes

There are limitations in the discussion due to the reliance on external links for problem context and potential missing assumptions in the calculations presented.

Who May Find This Useful

Students and individuals interested in torque calculations and strength of materials may find this discussion relevant.

Fixed, thanks
 
Nobody? Am atleast on the right track? I wish there was a way to check these sort of problems.
 
You might check your torque calculation. Using the numbers you are using, the equation should be (torque will be in ft-Lbf): [tex]P = \frac{T \omega}{5252}[/tex]

I would do a quick and dirty compare using a rule of thumb based on distortion energy

[tex]T = \frac{\pi d^3}{16}(.58 S_y)[/tex]

I think you've got the right idea though.
