Solid shaft compression - taper locks

AI Thread Summary
The discussion focuses on determining the stress on a solid shaft subjected to compressive forces from taper locks or press fits. The original poster is uncertain about the maximum allowable hoop stress when the internal radius is zero. They question whether steel can withstand more than 250 MPa in this context, especially when a locking ring applies 220 MPa to the shaft's exterior. Despite calculations suggesting insufficient strength for a shaft with a 65 mm outer diameter and 1 mm inner diameter, the poster believes it would still function effectively. The conversation highlights the complexities of stress analysis in solid shafts under compression.

Hi all,

I am trying to work out the stress on a shaft when a compressive force is placed on it such as a taper lock or press fit. I have looked at all the thin and thick wall section formulas and they seem ok. I am not sure what happens when the internal radius becomes 0 and its a solid shaft.
What is the maximum stress (hoop) allowable. For example surely steel can take more than say 250 mpa if it is a solid shaft being clamp.
What compression should a steel shaft be able to withstand,
Thanks all, too many hours scratching my head on this one.
 
Engineering news on Phys.org
Just to make things clear i am looking at a locking ring that applies 220mpa to the outside of the shaft, and using these equations even a shaft with a with 65 mm od and 1 mm ID it isn't strong enough but i know it would work.
Thanks all
 
Here's a video by “driving 4 answers” who seems to me to be well versed on the details of Internal Combustion engines. The video does cover something that's a bit shrouded in 'conspiracy theory', and he touches on that, but of course for phys.org, I'm only interested in the actual science involved. He analyzes the claim of achieving 100 mpg with a 427 cubic inch V8 1970 Ford Galaxy in 1977. Only the fuel supply system was modified. I was surprised that he feels the claim could have been...
Thread 'Turbocharging carbureted petrol 2 stroke engines'
Hi everyone, online I ve seen some images about 2 stroke carbureted turbo (motorcycle derivation engine). Now.. In the past in this forum some members spoke about turbocharging 2 stroke but not in sufficient detail. The intake and the exhaust are open at the same time and there are no valves like a 4 stroke. But if you search online you can find carbureted 2stroke turbo sled or the Am6 turbo. The question is: Is really possible turbocharge a 2 stroke carburated(NOT EFI)petrol engine and...
TL;DR Summary: Heard in the news about using sonar to locate the sub Hello : After the sinking of the ship near the Greek shores , carrying of alot of people , there was another accident that include 5 tourists and a submarine visiting the titanic , which went missing Some technical notes captured my attention, that there us few sonar devices are hearing sounds repeated every 30 seconds , but they are not able to locate the source Is it possible that the sound waves are reflecting from...
