Torsional Shear Strength of steel tubes

AI Thread Summary
The discussion focuses on the lack of empirical equations for estimating the torsional shear strength of steel tubes, with estimates varying between 57% and 75% of ultimate tensile strength (UTS). Participants express a need for reliable data based on UTS or yield strength. A member recommends using a specific resource for shear and tensile relations. The conversation highlights the importance of empirical data in engineering applications. Overall, the quest for accurate torsional shear strength calculations remains a key concern among the contributors.

Does anyone have any empirically based equation for estimating torsional shear strength of a tube made from a given steel. I've seen "estimates" ranging from 57% UTS to 75% UTS, but nothing empirical. I'm open to anything based on UTS, a given offset strength, or JAEL yield. Thanks!

Thread 'Race car suspension Class'

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
