I guess there are several different types of humor, some of which will translate and some will not. Puns probably don’t translate, but physical humor probably does. Narrative jokes probably are somewhere in the middle. They usually rely on a sense of surprise or impropriety. Those are more...

If the rule is personal preference then my personal preference is simply to acknowledge that the quantities have different dimensions in different systems of units. I personally prefer to have one simple rule. To me personally that is far clearer than trying to guess which unit the constant is...

Yes, it is dimensionless in SI units, but not in imperial units. In imperial units it is ##0.031 \mathrm{\ lbf \ s^2 \ lbm^{-1} \ ft^{-1}}##. So where did ##k## get absorbed in SI? So, in the process of making ##k## dimensionless in SI units, which quantity had to change to accommodate the fact...

It seems to me that the rest follows from this.

What program do you use for the drawings? I use solidworks but don’t typically make draftsman style output.

When you make ad-hominem statements then other people getting upset is precisely what you intended. It is both too late and also disingenuous to then pretend to some moderation of discourse. Particularly when @weirdoguy actually responded politely, showing that both your posts were intended to...

As an exercise for you, trace why the constant ##k## in Newton’s 2nd law, ##\vec F_{net}=km \vec a##, doesn’t exist in SI units. Also, if you want to assert that ##k## does exist in SI, but is absorbed somewhere, then where is it absorbed and how do you know it was absorbed there and not...

Yes. You are emphasizing the dimensionless physical comparisons here. Not the value in some units. This is indeed governed by the fine structure constant.

No. If ##c## is a dimensionless 1 then you could equally say that it was absorbed into the space coordinate. Or that its cube was absorbed into the time coordinate and its fourth root was absorbed into the space coordinate. Far easier to just say it just doesn’t exist in those units. There is no...

You publish it in the professional scientific literature. Just like scientists have done for centuries. Even an elementary school child can be published in the professional scientific literature if their scientific work is good. You can follow Ryo Shibata’s example...

The dimension of a quantity also depends on the system of units. The dimension is a convention adopted by the unit system. This is the big lesson of Gaussian and other cgs units. They are not just different sizes of the same quantities, but dimensionally different quantities. When I say...

That is true enough. I used Timberloks for our chicken houses and goat shed. All are subject to repeated forcible movements over time. Your aquarium is not the same kind of load.

This is a much better question, and is getting close to the type of thing that you have to do in order to understand how important the values of the dimensionless constants are. So the main thing that you have to do is decide what is different in the two universes, and what is the same...

With members that large most traditional joints will be very strong and stable. You could easily get 30 or more square inches of long grain glue surface per joint with a half lap or mortise and tenon or similar. The Timberlok screws are very strong in shear, but they will not prevent racking...

Yes. Anyone who wishes to can go through the exercise I linked to earlier to see that.
