AI Thread Summary
To calculate the torque required for a sphere to exit a countersink, the key factors include the force applied by the spring, the dimensions of the sphere, and the geometry of the countersink. The spring exerts a force of 76.26N at a compression of 11.6mm, while the sphere has a fixed diameter of 6.0mm and the countersink measures 0.5mm with a 45° angle. Understanding the interaction between these components is crucial for determining the torque in Newton-meters (Nm) needed to prevent motor issues in a coffee milling appliance. Additional clarification or visual aids may be necessary for precise calculations. The discussion emphasizes the importance of these variables in ensuring effective operation.

I need help (in a very simple way) due to calculate the torque needed to let a sphere coming out of a countersink.
I'll try to explain better my application with the components involved:
1. a spring that apply a Force F=76.26N (nominal length 14mm) at 11.6mm of compression: these values could be variable;
2. a ball bearing sphere 6.0mm diameter: this is a fixed value;
3. a countersink of 0.5mm x 45° in a 5.0mm hole (the height and the angle could be variable);
The spring push the sphere inside the countersink hole.
The countersink holes are cnc in a coffee milling appliance and I need to know the torque in Nm to let the sphere coming out of the countersink (this is used to avoid problems on the driving motor).
If needed I can try explain better with a drawing.

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...
