AI Thread Summary
A user seeks advice on limiting the rotational motion of a shaft inside a fixed cylinder, requiring it to remain stationary until a specified torque is reached. They are exploring options like surface-to-surface friction with known coefficients of friction and contact area, or hydraulic methods, while avoiding electric power or MR fluids. A suggestion was made regarding a torque limiter clutch with a fixed output shaft, which aligns with the user's needs. The discussion emphasizes finding a mechanical solution to achieve the desired torque control. Overall, the focus is on practical, non-electric methods for torque limitation.

First time poster here, thanks in advance!

I have a project I'm working on, and I'm looking for a way to limit the rotational motion of a shaft inside a cylinder. The cylinder is fixed, and the shaft is spinning inside the cylinder coaxially. Basically, torque will be applied to the shaft, and I need the shaft to not spin relative to the cylinder until a specified torque, then it can "break free" and start to spin.

Anyone have a good idea on how to limit this motion? Surface to surface friction with known COFs and contact area? Hydraulically somehow?

I'd like to do it without the use of anything like MR fluid or needing electric power. Don't know if that's possible, but figured I'd throw it out here for some thought.

Thanks!

Ah, yup. Something just like that is what (I think) I'm after. Thanks!
 
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
