The microwave will create a set of standing waves in the 'box'. These waves are formed from the left (notice the mica plate, which appears off-white and acts as a waveguide) and reflect back from the right metal panel. The wavelength of these waves is approximately 12.8cm, because microwave radiation inside microwave ovens (and the resonant frequency of ...

It is an incomplete and vague question. Needs the geometry and material properties of the table and the legs. Consider a thin big table. It will deflect so much under the load into a hyperboloid that it will let the legs' connection to rotate offsetting them from being vertical, making a wider base, causing the P delta effect, leading to collapse of the ...

Logically I would use 4 bolts. Since you expect a moment to develop in the y axis and x axis you ought to have bolts suffice to resist those forces with a safety margin of 1.15 of the maximum allowable force. An additional 2 bolts through the vertical face would be a good idea by extending the lip upwards to the top of the bearing case that these new bolts ...

In general the idea of bolt connections is that there should be no stress on the holes themselves. The purpose of bolts is to push the surfaces together so that the friction between the surfaces takes on the stress. So its important that the torque on the bolts is correct and the primary force direction isnt upwards in this case. (If it is bolt from sides) ...

Just buy a proper worm gear (Don't ask me where, here in Germany I'd try Aliexpress). Should only be the equivalent of a few €, wherever you are. You want a cost effective solution but consider the time you spend on your approach. There's also a solid technical reason for a proper worm gear: This is for a hand driven orrery. On a worm gear with a straight ...

Papermaking uses rollers called Spreaders to spread the sheet out in the cross-direction (perpendicular to sheet movement). These are bowed rollers that use friction against the sheet to spread, and I suppose you could use it to compress a sheet. For such a small scale you would need to build it yourself. I feel like the design you show will only emboss ...
