They are based in Germany. Another ...

You're going to struggle to get a reliable gas tight fit with that design. For a start it would be better if the two connections were separate so they aren't fighting against each other in terms of fit. Equally rather that trying to reinvent the wheel you would be better using off the shelf connectors which are known to work. It would be fairly trivial ...

It's simple: while B is a pinned support, C is a roller. You can see that in the figure, where B is drawn clearly bolted to the "ground" while C isn't. In fact, the contact between C and the "wall" seems to be a wheel of some sort. Rollers don't have to "prevent only the vertical [translation]". They have to prevent translation in one direction while ...

If you have to use the Teflon for some reason(s), you can bond the Teflon part to the SS by first etching the Teflon with a special etchant designed for Teflon and then you can use a high temp epoxy adhesive to get a good bond (seal) between the two assemblies.MasterBond Inc. has a large selection of epoxies for all kinds of applications. I would sandblast ...

The rod BC is a two force member. Therefore, the forces on either end must be along the axis of the member. i.e. since the rod is horizontal, the forces on either end can only be horizontal. The beam AGDE is not a two force member. Therefore, it can have forces on the ends in both directions. In other words, the reason that the reactions are different ...

Full penetration weld would be ok. I am more concerned about that bolts between the beam and the concrete edge. It could be difficult to tight them and inspection would be problematic too. Also you loose a considerable part of the flanges, at the beam edge, and therefore you cause a severe drop of the moment strength. I don't know if this is acceptable for ...

Yes it can, and in many designs it should be a pin support along one axis and fixed support along other. In many trusses and bridges that is the case. The design software when defining a joint have the joint degrees of freedom choices. Among those are the option to define the joint a hinge along one axis but fixed along the others. You can even have joints ...

There are many, many different commercially-available designs of fluid connectors that shut off automatically when disconnected and open up when connected. They are available in plastic and metal, permanent and disposable, in all sorts of sizes. Try a search on "make-and-break fluid connectors".

The image is poorly focused and laptop name is not specific to identify model, but it appears to be a Lenovo YOGA 3 Pro, 6 pin USB/charging port. The USB port is dual purpose. USB and charging (20V). By default, it is set up as a USB port. This is a problem because the voltage changes dependent on mode. The 5.2V rail has to be disabled to become the 20V ...

Twin port connection. Usually for voltages under 25Vdc. It also has a restrictor edge to ensure it can only connect one way... the correct circuit designed way.

Use a nut or threaded boss fixed or welded to the plate.

A few design improvement notes: PTFE is not Nylon. I'll assume from here on out you really mean PTFE here, but it's better known as Teflon. Nylon would be done entirely differently. You can't just snap these two parts together for an airtight seal. You can get mostly air tight, but you will not make an airtight seal between stainless and PTFE with just a ...

If you can modify the stainless steel prongs with groves or indentations to accept either O-rings or Compression brass or plastic fittings you would not need any adhesive! Plastic compression connectors can withstand high temperatures and pressures.

There's really not enough information to be certain, but the images seem to match TR Fastenings' "Self Clinch Non-Locking Mini Squeezed Nut" N.B. It also looks to have been improperly installed, as the 'spiked' diameter should be fully embedded in the bulk material.

Use some steel channel and have the pieces slide in and out, but you will see that this type of board will suffer damage... The steel or aluminium channel is available at many stores...
