comment Why Two Equal Resistors Cut Voltage in Half?
If you have a 10k and a 3k, then add another 3k, the total is now 16k, so the 10k now drops 62%, and each 3k drops 19%. The equivalent values resistors still drop an equivalent amount of voltage.

comment Why Two Equal Resistors Cut Voltage in Half?
Now you're changing this, but you have to evaluate percentage OF TOTAL. Two 3k resistors in series = 6k ohms, each taking 3k/6k = 50%. A 3k and a 10k resistor in series = 13k ohms, the 3k taking 3k/13k = 23% and the 10k taking 10k/13k = 77%.

comment When does the wagon-wheel effect occur?
The effect being described in the question does not necessitate two wheels or a strobing light source, it can be observed with a single wheel and continuous light source.

What do $f_1$ and $f_2$ represent in the context of a single spinning wheel?

comment Could this planetary superalignment happen?
The sun does count. Many 'planetary alignments' are based on aligning 'in the sky', and being collinear without solar inclusion. Here's an example of such an alignment: modernsurvivalblog.com/wp-content/uploads/2011/05/…

I want 8 planets, a star, and the Earth's moon to be in alignment. 10 bodies.

Thanks for the info, I'll review the details when I get a chance. I'm beginning to realize that what I'm after is something different than the typical definition of planetary alignment, and includes a solar and lunar alignment in the same gravitational direction, in other words Mars through Neptune are across the Sun.

@Qmechanic I have read it, and I disagree that it applies to this question. I'd be happy to discuss in chat.

I'm only interested in said planetary alignments to demonstrate a maximal upper bound on planetary alignment effects (and likelihood/frequency) to provide a response to these 'zero-g day' posts. I want this to contain a full response for anyone googling 'zero g days' or gravitation effects of planetary alignments, thus the information is important (to me).

@DavidZ, I'd prefer not to remove it as the spirit of the initial question was about both magnitude/effects and possibility/timing; I was just pushed into answering the first part myself. They belong together in my opinion, jointly explaining superalignment.

No @lionelbrits, it is not a duplicate. That question is asking about simple collinearity of all 8 planets; I'm asking about a specific form of collinearity where the gravitational forces are maximally additive.

comment Could this planetary superalignment happen?
The calculation component could have been done before, in which case a link would suffice and save a deal of time, and I'm unaware of where I can find 'time to specified alignment'. What stops you from answering it? This is a question AND ANSWER site, after all.

comment Could this planetary superalignment happen?
I never said it did? I'm looking for an answer to $\frac {F_g - F_{moon} - F_{Venus} - F_{Mercury} - F_{Sun} - F_{Mars} - F_{Jupiter} - F_{Saturn} - F_{Uranus}- F_{Neptune}} {F_g}$ when they are in a particular collinear arrangement such that they are all constructive, and also if this arrangement is possible and if so how often it will happen / how soon until the next one, and I was assuming within a suitable margin of error this would happen at least once before the solar system became unstable.

I'm not after minimum distance of each planet summed; I'm looking for maximum cumulative gravitational effects (Jupiter, for example, would be across the Sun). Also, how would it be possible to answer how often (if ever) said alignment with as much error margin is necessary would occur?
