AI Thread Summary
The discussion focuses on identifying the specific grades or codes of Brass and Cast Iron used for worm wheels. Participants emphasize the importance of conducting thorough research, suggesting that a simple Google search can yield valuable information. The British Standard, BS 721, which pertains to worm gearing specifications from 1963, is mentioned as a relevant resource. The conversation encourages asking specific questions based on findings rather than seeking general answers. Overall, the thread highlights the need for independent research while providing a reference to established standards.

I have Mass A being pulled vertically. I have Mass B on an incline that is pulling Mass A. There is a 2:1 pulley between them. The math I'm using is: FA = MA / 2 = ? t-force MB * SIN(of the incline degree) = ? If MB is greater then FA, it pulls FA up as MB moves down the incline. BUT... If I reverse the 2:1 pulley. Then the math changes to... FA = MA * 2 = ? t-force MB * SIN(of the incline degree) = ? If FA is greater then MB, it pulls MB up the incline as FA moves down. It's confusing...
