AI Thread Summary
The contact patch between a 0.5 mm radius and a 3 mm diameter ball is described as a point, indicating it has location but no dimensions. The discussion highlights the relevance of Hertzian contact stress, which examines how radii, modulus of elasticity, and contact force influence internal stress and contact area. Participants are encouraged to explore these factors for a deeper understanding of contact mechanics. The inquiry emphasizes the complexity of calculating contact patches in physics. Understanding these principles is essential for applications in engineering and material science.

TL;DR Summary
Contact area between diameter and a radius
Hello friends!
What is the contact patch between a radius of 0.5 mm (0.020”) and a 3 mm (0.125”) diameter ball?
All i can find is that it it a Point. And points have location not dimensions.

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...
