Funny thing, I wrote the email below last Sunday and thought, do the world's callers really want a physics calculation on their mailing list? I decided the better of it and didn't send it. Ok, I guess I was wrong...
What I call support is against centrifugal force, not vertical. Of course, there's no need to lift the other dancer, and it's a really poor idea. As Jeff pointed out, in a fast swing, there's a lot of centrifugal force, as seen from our rotating frame of reference in the swing. For physics buffs, centrifugal force increases as the square of velocity, so a swing that goes around three times in 8 beats rather than twice (1.5x faster rotation, the first-level "fast swing") has 2.25 times as much outward force to support. Estimating a 25 cm radius (about 50 cm between the centers of mass of the two dancers, in the middles of their abdomens, which I measured with a tape measure) and a 70 kg (150 lb) dancer, that's an outward force for each of the two bodies of almost 390 Newtons, or nearly 90 pounds. Much of that will be borne by the friction between the dancer's feet and the floor, but the rest will be held by the supporting dancer(s). How much depends on how they lean. For a standard swing (2 rotations per 8 beats), it's just under 40 lbs. Fortunately, you only have to hold it for four to eight seconds at a time, or actually less as you accelerate and decelerate inside that time, though the peak force will then be higher. ...and now I add... Despite starting with it above, myself, I think we're somewhat misleading ourselves with this Mv**2/r calculation. The key thing here is that a centrifugal-force calculation (centripetal, actually) makes some assumptions that we dramatically violate when we dance. We are not rigid bodies. At best, we're collections of many light rigid bodies (our bones) linked by ligaments, tendons, and muscles, and bearing all sorts of other masses that move relative to one another, storing momentum until we can deal with it in the next step. We effectively pump momentum up from our feet, into our bodies, and down to our feet on each step. We transfer it to the other dancer through our arms and theirs, and their back, if we have a hand there. With that in mind, consider this model of a swing. Each dancer's upper half is trying to execute rigid circular motion. Our lower bodies (hips down) are doing something else, and half our mass is down there. So, drop my estimated 90 lbs to 45 just for that (I'll drop it more in a minute). The lower half is essentially stepping a figure with 90 or 135 degree corners on each beat. Consider the left foot. In a standard swing (2x in 8 beats), it is walking a square, directing momentum along the sides of the square that the upper body picks up and turns into rotation. Half of each square side brings that leg closer to the middle, the other half takes it farther away. We land, push off, and do it again and again. That push-off supports the centripetal needs of both legs (through the hip joint) and some of the upper body. If there is an outward lean off the right foot, additional centripetal support is needed from either the legs or arms. The right foot is mainly a pivot, while both feet support gravitational weight. Good dancers constantly adjust how far out their left feet land on each step and how hard they push off, simultaneously satisfying both their centripetal needs and the required spin rate. This lets them control how much inward force they draw from their feet into the upper-body rotation to supplement the arms. That reduces the support needed from the arms well below 45 lbs. It can reduce it to zero. Tweaking the lean also adjusts where the axis of rotation is, to balance the different masses of the dancers and make their differing force impulses produce matched torque impulses. Dancers use the beat to step in sync with the other dancer's legs, or these torque impulses would come at different times, and the swing would wobble and fall apart, as Chris Lacey alluded to. So, yeah, it's complicated, yet even children solve this problem when they swing. Everyone is an intuitive physicist! And, each time I think about this kind of thing, I get more amazed at the engineers who make robots. Has anyone taught a robot to do a contra swing, yet? --jh-- On Sun, Mar 24, 2024 at 3:24 PM Julian Blechner <juliancallsdan...@gmail.com> wrote: > Hi Joe, > > You mean, palms flat on the back of shoulderblades?
