    Direction Torsion
AI Thread Summary
In a circular bar subjected to torsion, shear stresses are present on the surface, with maximum values at the circumference and zero at the center. The discussion highlights that while shear stresses vary linearly in the radial direction, they are primarily circumferential and axial in orientation on a planar element. This raises the question of why radial stresses are not considered in this context. The focus remains on understanding the nature and direction of shear stresses in torsion. Overall, the analysis emphasizes the significance of shear stress orientation in torsional loading scenarios.

In the fig. attached below,a circular bar is subjected to torsion. A point is considered on the surface of the bar(denoted by point 1). The shear stresses are shown .
Why don't we take one of the stresses in the radial direction??

The shear stresses vary linearly in the radial direction, from 0 at the center to a max of TR/J at the circumference , but the direction of those stresses on a planar element are circumferential and axial ( longitudinal) only.
 

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 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

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
