Contact Cylinders Stress

Click For Summary

Hertzian contact stress refers to the localized stress that occurs when two curved surfaces come into contact, such as two cylinders. This stress is critical in determining the performance and lifespan of mechanical components like bearings. The discussion emphasizes the importance of calculating contact pressure and understanding deformation under load to prevent failure. Key factors influencing Hertzian stress include material properties, surface roughness, and the geometry of the contacting bodies. Accurate analysis of these stresses is essential for reliable engineering design and maintenance.

Thread 'UV filter for home central heating?'

Had my central air system checked when it sortta wasn't working. I guess I hadn't replaced the filter. Guy suggested I might want to get a UV filter accessory. He said it would "kill bugs and particulates". I know UV can kill the former, not sure how he thinks it's gonna murder the latter. Now I'm finding out there's more than one type of UV filter: one for the air flow and one for the coil. He was suggesting we might get one for the air flow, but now we'll have to change the bulb...
