forces on a pin in a pressurized chamber
forces on a pin in a pressurized chamber
(OP)
Hi,
I have a confusion. The question is if a solid pin is inserted in a pressurized chamber(5000 psi) with both ends sealed, as shown in the attached picture then how much force is required to pull the pin back. will pressure have any effect on resisting the pulling force. kindly help
Regards

RE: forces on a pin in a pressurized chamber
depends, the simple answer to match the simple sketch would be no.(till the retracting end enters the fluid boundary)
If a real situation, then the seal design and fluid may cause the pin retraction to be harder with pressure verses without
RE: forces on a pin in a pressurized chamber
The required force is simply twice that required to overcome drag of the sealed ends. Given the typical elastomer squeeze, then it is quite simply static coefficient times normal load imparted from your seal element, twice of.
You gave a word problem, therefore a word answer.

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.
