A video that covers a multitude of washer types, where to use them and why. Rather well done.

AI Thread Summary
The discussion centers around a video that explores various types of washers, their applications, and the reasoning behind their use. Participants express admiration for mechanical engineering, highlighting the design features that prioritize safety, such as the use of shear studs to protect the main chamber during pump failures. There is a humorous remark about the washers potentially being lost in orbit, suggesting a light-hearted take on the challenges of mechanical assembly. Overall, the conversation emphasizes the importance of understanding washer types in engineering contexts. The video serves as an informative resource for those interested in mechanical components.

Great video!
I am constantly amazed at mechanical engineering. The guys would specifically call for mounting studs that would shear off the bolts before destroying the main chamber in case of a catastrophic pump failure.
Those washers holding these down are likely in orbit as we never found them.

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...
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...
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...
