I'm thinking about it, but my likelihood of following through based on
interest and difficulty is probably single digit percentages.
The main reason is knowledge as Jeff said, but I do think we could improve
teaching if we had a deep knowledge of this stuff.

Does anyone have any thoughts about how we can measure some of this? I can
definitely imagine a force pad on someone's back to measure the tension,
but I'm a bit lost as to how he can measure the ground forces (including
possibly torque around a vertical axis)?
I think normal force should be
I addressed this in my other email, but this is a good example. In this
case my back is providing 100lbf to your hands.
I also can't imagine being in this position and having centers of mass two
feet apart, but I would want to measure it before making this an argument,
hence going with your
There's actually another factor of two if you both have your hand on the
other person's back or shoulder. To get the needed centripetal force, you
both are contributing.
You might say, "you need to lift me and I need to lift you" but that's not
quite right, because my shoulder is lifting your
I think you're trying to calculate two 150lb dancers, but you've calculated
for a 300lb mass, but you shouldn't do that doubling. I'm exerting enough
force to provide your centripetal force and vice versa. Those forces oppose
one another, but they don't add up. That is a factor of two error.
I
The point is that if you announce it loudly, then you're making it gender
free in name only. If larks is just code for gents, then people who want to
dance a role that doesn't match their gender expression or identity (or who
are non-binary for that matter) will be more uncomfortable than if the
I like Star L -> Circle R or Star R -> Circle L (or vice versa I suppose)
so that the dancers can maintain momentum for that transition. I don't
think switching either the stars or the circles affects how it interacts
with the rest of the dance, so either switch would work.
