Why Is the Force for T1 Doubled in the Torsional Deflection Problem?

AI Thread Summary
The discussion centers on the confusion regarding the force for T1 being doubled in a torsional deflection problem. It is clarified that the 3-inch section is responsible for resisting both loads, while the 2-inch section only resists the outer load. This distinction in load distribution explains why the force for T1 is calculated as 4000 in-lb. The participants confirm the understanding of how the sections interact under load. Overall, the doubling of the force for T1 is attributed to the combined resistance of the 3-inch section.

Thread 'A practical way to vaporize fuel for high MPG?'

Here's a video by “driving 4 answers” who seems to me to be well versed on the details of Internal Combustion engines. The video does cover something that's a bit shrouded in 'conspiracy theory', and he touches on that, but of course for phys.org, I'm only interested in the actual science involved. He analyzes the claim of achieving 100 mpg with a 427 cubic inch V8 1970 Ford Galaxy in 1977. Only the fuel supply system was modified. I was surprised that he feels the claim could have been...

Thread 'Turbocharging carbureted petrol 2 stroke engines'

Hi everyone, online I ve seen some images about 2 stroke carbureted turbo (motorcycle derivation engine). Now.. In the past in this forum some members spoke about turbocharging 2 stroke but not in sufficient detail. The intake and the exhaust are open at the same time and there are no valves like a 4 stroke. But if you search online you can find carbureted 2stroke turbo sled or the Am6 turbo. The question is: Is really possible turbocharge a 2 stroke carburated(NOT EFI)petrol engine and...
