Torsion Test Demonstration: Cast Iron and Carbon Steel

[@Soup4Dayz]

What an amazing demonstration! This really displays what I'm learning in my Strength of Materials class, that the more brittle material, which has a shorter elastic region on the stress-strain graph will reach the point of permanent deformation much earlier, but with a higher stress requirement.

Thanks - glad you found it useful

Not all brittle materials have shorter elastic region. The better way to tell brittle material apart is the absence of permanent (plastic) deformation.

Nice video. I think it would be better if you could depict the stress-strain diagrams.

Thanks Daniel - this follow-up video shows the use of this data in developing a diagram of stress against angular twist in radians. ua-cam.com/video/qZs9IkG179Y/v-deo.html

what is the procedure to calculate these output (torque and angle of twist) theoretically?

[@EngineersAcademyLTD]

Thank you for your question. There is quite a complex formula known as the torsion equation. It is probably a bit difficult to go into here, but we will be posting videos on this topic soon.
