AI Thread Summary
Allowance stress in vessels refers to the maximum stress that materials can withstand without failure, which can include tensile, compressive, or shear stresses. In the context of thin or thick-walled vessels, the specific type of stress may not be defined, so it is advisable to treat it as a general upper limit. If there is uncertainty about the type of allowable stress, it is recommended to seek clarification from the instructor. Understanding these stress types is crucial for ensuring the structural integrity of the vessels. Clear communication about stress specifications is essential in engineering discussions.

HI. :)

help me please.

when the problems says that there is an allowance stress, especially in thin or thick walled vessels, what kind of stress could it be?

thanks!

If the type of allowable stress is not specified (e.g., allowable tensile stress, or allowable shear stress), assume that the allowable stress is a general upper limit. If that doesn't feel right, seek clarification from the instructor.
 
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...
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
