AI Thread Summary
Fluid dynamics significantly complicates airplane toilet design due to the need for efficient waste management in a confined space. Engineers must consider factors like sediment buildup in pipes, which can lead to costly repairs if not addressed during the design phase. Testing for these systems, while unglamorous, is crucial for ensuring reliability and functionality. Anecdotes about testing experiences highlight the often overlooked challenges faced by engineers in aerospace. Overall, the complexities of fluid dynamics play a vital role in the development of effective airplane toilet systems.

I have to say that it is impressive that they're development testing includes that. It's definitely not glamorous, but it is necessary. I have read a lot of case studies on piping designs in which the designers didn't take into account the ID of the pipe reducing over time due to sedement build up, etc...It's very costly to go back and fix something like that.

It sounds like a test I would get stuck doing. I seem to always get the unglamorous tests.Not to derail the thread, but speaking of very unglamorous testing...this reminded me of some tests a dynamics professor I had in college had to do when he was working on the original space shots and sending monkeys up. Hillarious stories.

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

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...

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
