How to calculate changes in the radius of a surface under compression?

AI Thread Summary
To calculate changes in the radius of a surface under compression, it's essential to understand the type of load applied, whether uniform pressure or localized forces. Knowing the initial radius and the percentage of surface compression is crucial for determining the new radius. The discussion highlights the need for clarity on the nature of the material, such as whether it is a solid metal cylinder. Accurate calculations depend on these parameters to derive the percentage change in radius effectively. Understanding these factors will lead to a more precise calculation of the radius changes.

How do i calculate percentage of changes in radius, when the surface which cause the radius, will be compressed by a certain percentage?

To illustrate better, i have drawn the picture of the question. How to calculate radius ?? if radius A Is known. Changes in the surface is also known. Thank you very much beforehand.

Welcome to the PF.

Is that a solid metal cylinder? What is causing the change in the radius of the cylinder?
 
Do you mean "pressure" which would imply uniform load all around the circumference of the cylinder; or, a load applied along two opposite sides of a cylinder?

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

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...
