Now I started to think that as people have said the forces F1 and F2 have to be equal naturally. However, would the pressure distribution on the plastic rod depend on the rod diameter?

No, it is not impossible topology. We cannot share images of the actual device but it is pretty much wrapping a wire around a plastic rod, and then attaching those wires to a "ring". Of course you need to have grooves in the ring to guide the wires etc. but they are not important to the forces...

I understand that I might have oversimplified the problem a bit. Mechanically what happens in the device: 1. The plastic rod placed inside the wire (see figure 1). 2. The positions A and B are moved so that the wire is tight. Now, these positions depend on the rod diameter. 3. When wire is...

We have a following setup (see below). A plastic rod is placed inside a plastic ring. A wire is wrapped around a plastic rod from which it goes to the outer surface of the plastic ring. The friction coefficient between the wire and the plastic ring is about 0.1. We have several different sizes...

Thanks, just to verify that w is the width?

Thanks, the pressure range is from 6 kPa to about 33kPa.

I have a zip-tie like structure, which when pulled, squeezes an elastic part. Think of it like a having a zip-tie around your finger. I can measure a force that is related to the squeezing pressure. This relationship between force and pressure is quite linear. I would now need to create a...

I have following setup where a non-elastic belt is wrapped around an elastic object, like leather belt around waist. When I pull the belt with force F, it tightens around the elastic object and the belt exerts force to the elastic object. I would like to know what is the relationship between the...

Hi, Here is a diagram of the problem. The steel plate could be made from some spring steel grade, eg. SAE 1080. The idea is that the plate functions as a spring so we have a repetitive cycle from straight to arc and back again. Of course in real life the plate could be pre-bent just a bit, so...

Well, definitely not a homework. Haven’t done those in a decade. I stumbled into this problem in one design where a tall coil spring was used in a very space limited application. I started to wonder if the coil spring could be replaced with a thin metal sheet which would be bent into an arc by...

Hi, If I have a straight beam and I start to push its ends towards each other with force F, the beam will obviously bend into an arc. What is the height/amplitude at the center of the arc when the beam length is l and the beam ends have been displaced by d. How much force (P) the center part...
