AI Thread Summary
The discussion centers on a problem involving the inflation of a plastic ball that generates tangential stresses, with specific stress values and material properties provided. Participants emphasize the need to identify knowns and unknowns, relevant equations, and the possibility of establishing a system of equations to solve for the unknown thickness after inflation. The conversation suggests that the problem resembles a homework question, indicating a preference for guiding rather than providing direct answers. The thread was later moved to a dedicated homework section for more focused assistance. Overall, the emphasis is on understanding the principles of stress and material behavior in inflated structures.

A plastic ball is inflated enough to produce tangential stresses. Stress X = Stress Y = 2000Kpa
The radial thickness of the material is 1.2mm brfore inflation. Find the thickness after inflation if the tensile modulus of elasticity is 3.4Gpa and the shear modulus is 1.4Gpa.

this looks very much like a homework problem, so chance are you won't be getting the answer- "teach a man to fish"

list your knowns and unknowns
what equations are relevant?
can you set up a system of as many equations as there are unknowns?

Thanks Jehan, I have moved my post to the homework section.
 

Thread 'Bubble formation in 4 mm gap vessel'

How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...

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...

Thread 'Find 3D Printer & Software Resources for Prototype Creation'

I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
