AI Thread Summary

An efunda account costs $36 per year and offers access to resources without interruptions. Users express frustration with being locked out mid-task, prompting consideration of the subscription. Many believe the trial approach is reasonable, suggesting that if the service does not meet expectations, one can choose not to renew. The general sentiment is that the investment is low, making it worth trying. Overall, the discussion leans towards a positive outlook on the value of an efunda account.

I'm thinking about getting an account on efunda (being sick of getting halfway through something before it locks me out). Does anyone here use efunda and think it's worth $36 for a year?

It is only 36 bucks. How bad can it be? I would spend the money, try it out, and then make a decision to renew my account. If it isn't worth it, then don't rejoin.

Thanks

Thread 'Bubble formation in 4 mm gap vessel'

How did you find PF?: Via Google search 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...

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 'Find 3D Printer & Software Resources for Prototype Creation'

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...
