Sorry, I meant to say the latter in the original post (I can't update it for some reason)

I'm trying to rotate a shaft 60 degrees every 30 seconds; right now I'm looking into some sort of toothed gear / ratchet powered by a linear solenoid actuator... I'm still working on figuring out the details but it could work. do you guys agree with that or should I be looking at something else ??

Does anyone know of a cheap mechanical device which is able to achieve specific intermittent / discrete motion along a shaft?

I'm designing a system that will thermally cycle a stainless steel substrate up to 1200C from room temperature; right now my design consists of clamping the substrate onto a plate using a bolt head/washer with a nut on the other end of the screw, as shown on the attached figure. I want to...

I'm designing a device that will expose substrates plasma sprayed with YSZ over various temperature gradients periodically. A CAD drawing model has been attached with what I've got so far. The way I'm planning on this working is that a shaft will be fitted the holder and a sprocket-chain...

I'm planning on using a steel shaft with a steel bearing. I just found this site, http://www.roymech.co.uk/Useful_Tables/Tribology/Bearing%20Friction.html, which calculates the bearing friction; how can I determine the radial load from the given info ?

What do I need to do in order to figure this out ?

Presumably the torque required to accelerate the shaft to 100 RPM All I know is that I selected a cheap motor capable of providing 100 RPM for this design and my professor yelled at me for not including 'Torque considerations' Am I misthinking this ?

Hello, I apologize if this question appears simple; it may be but I cannot find the answer in any of my textbooks. I want to turn a shaft with a diameter, d, and length, L, which has a plate attached at the end, of diameter D. I made up a side view of what I'm trying to illustrate in...

Hi, I've used complex numbers before for contour integration, circuit theory, and analysis; the only problem is, I have no idea how to think of complex numbers, physically - no teacher, book, or website seems to offer me any adequate solution. Can anyone please help me ? I hate doing...

This is our first design project and as such is very simple. We only have to consider an axial tensile force and an applied torque. There will be no deflection considered, and it is purely design. Right now I'm looking for a lightweight strong material and have found some Spectra fibers, but am...

For my Mechanics of Materials class, we have a project where we are given a shaft three points, with specified lengths in between each point, a specified load at one endpoint, and an applied torque at the middle point. We get to decide the material and its structure (constantly changing...

Absolutely. I never would have figured that out without playing with my eraser; thank you so much for your help! I'm just assuming that the twist on point C has to be influenced by the material of the shaft part B to part C. Thank you so much for your help! This is for part of a bigger project...

I'm taking my eraser out again :confused: Ok I think I see what you mean, the angle of twist from point A to point B is the same as the total angle of twist at point C (...?) This is what I'm seeing with the eraser right now, and that would mean: \phiAB = ToLAB/GABIP,AB = \phiC But...

Well I'm supposed to calculate the angle of twist at point C, so I figure to use the applied torque at point B and use the properties of the shaft from B to C (shear rigidity, polar moment of inertia, and length) Where did I go wrong?
