Hello
Are there any engineers here?
In my spare time I like to build projects that I design in my head. My latest idea is to build an decagonal barrel about 30cm in diameter and width; out of 10 rectangle lengths fused together, fused to solid decagons on both ends.
It needs to be able to carry 340 1+1/16" chrome steel spheres inside it at 88 revolutions per minute continuously without any cracking or bending.
Assuming the walls are at least 10mm thick:
What order would you rate these materials in suitability? Which is best?
1. Acryllic 2. Polycarbonate 3. Polypropene 4. HD polyethene
Thank you for any ideas
