Usually when your boobs go back under your arms and are not very separate.

See bras that fit full on bottom boobs Wide rootĬhoose this if the part of your torso where your boobs are attached takes a big part of your chest. This seems like a more natural shape for larger boobs, it is quite normal that bigger/heavier boobs tend to be full on the bottom. See bras that fit full on top boobs Full on bottom If you do have boobs that are full on top choose this option. See bras that fit pointy boobs Full on top Mark this shape if you notice your boobs to more somewhat pointy. See bras that fit round boobs Pointy boobs Mark this option if your breasts are mostly rounded. To best depict these kind of variations we encourage to use the the breast shapes gallery. For example someone may have very wide breast root, while other can have a more mild bit still wide root. Keep in mind that all of these shapes can appear in combined manner and on different degrees. The following is a list of canonical breast shapes that can be used to describe certain attributes of your breasts.
We're attempting to build a gallery using real breast pictures so users can identify which match their breasts best. Refer to this to share and identify how do your breasts look.Īccess the breast shapes gallery Contributing to the breast shapes gallery We have a gallery of real breasts submitted by users. Once you're making a really big rocket, other constraints, like how high your factory roof is or how wide your train tunnels are, start to come into play, and you may have to get longer and skinnier than the aerodynamically optimal shape as well.Breast shape is a very important factor that affects bra fit. So that's where the basic familiar rocket shape comes from. Keeping the bottom end of the Sears-Haack shape cylindrical, or even flaring it out slightly, rather than boat-tailing, improves stability dramatically. For stability, you want to keep the center of pressure behind the center of gravity - this is why darts, arrows, and many rockets have fins at the back the fins add drag at the base, moving the center of pressure back and keeping the projectile stable. The tapered "boat-tail" at the back of the Sears-Haack shape, though, moves the center of aerodynamic pressure forward. (Note that the proportions of this particular example aren't part the definition of the Sears-Haack shape for minimal drag you'd have to have an impractical body of infinite length and infinitesimal cross section.) Sears-Haack is pretty similar to the German V-2 rocket body. So what am I missing? Where in my broad estimations / calculations have I made naïve assumptions?įor supersonic flow, the Sears-Haack body offers less drag than the shorter teardrop that's optimal in the subsonic regime. Now, rocket designers are reasonably smart folks, and have probably thought of this So, for a single stage rocket, I would assume a bullet shaped rocket with something like a 3:1 length to diameter ratio would be ideal for an Earth launched rocket.Īnd for a multistage rocket, the top stage would have something like a 3:1, and the lower stages something like 1:1 - 2:1 length to diameter ratios. Fabricating a sphere is much harder than fabricating a cylinder.An airfoil shape has less drag than a sphere.Launching a rocket requires passing through the atmosphere.I.e., Surface area (dry mass) to volume (fuel mass) ratios would be worse in a tall skinny rocket. Which, if it operated in a vacuum, would call for a spherical tank. What I mean is that an ideal rocket would have as little mass used for the tank structure, and hold the maximum amount of fuel. However, to me, many rockets seem very tall and skinny. Obviously there are many factors that go into the design of a rocket.
