Here we go again.
After a long period of time, I did found the way to create a new app using app inventor. A really useful tool for those like me that do not have a solid background with programming lenguages ( even I have tried to learn it several times). Anyway, app inventor provide enough tools to make this type of applications.
Check the app inventor web page..https://appinventor.mit.edu/
The new tool, Compression spring calculator, allow the user to obtain the torsional stress under different compresion conditions, as well as, under the graph screen, evaluate the stress up to the solid condition, getting in real time the result for each compression length.
Here you have some screenshots of the app:
There are thusands of pages, webs, references you can find in the internet.
Some of them are listed here:
- Efunda, compresssion spring
- Amesweb compression spring
- Compresion Spring Calculator
- Design Information 1
- Design Information 2
Do not forget to watch the manufacturing process of this type of parts.
